That was a very very accurate explanation of how quantum teleportation works! Even with the "questions" analogy. Bien jugado, Henry. Although I was expecting to listen something: because the teleportation can't be completly perform if the Earth's scientist doesn't tell the moon's scientist the answer of the question he asks to the original cat, *faster than light quantum teleportation is impossible*. He needs to send to the other guy that answer in the traditional way.
The name "quantum teleportation" really screws people up. It should be called quantum entanglement transference or something. It would only have something to do with transporting people or things if their quantum state was important to their makeup. Any quantum entanglement inside people is constantly being destroyed, so the assumption that to transport a person, you need to use quantum teleportation to include all their quantum states is quite dubious.
the thing I'm wondering about this kind of teleportation: What can we do about the matter that ends up rearranged on the transmitting end? According to this, it could basically be any arrangement of particles, which has me concerned it could be unstable or in some way hazardous
How does one find the product of the mortality of two animals? Who knows. Obviously, he's using some strange analogy, but it still did a pretty bad job of helping me understand. This is particularly apparent when you compare it to his more recent series on relativity which was excellent.
11:03 "after we beam them the message..." this is a pretty important bit that most people miss and instead think the teleportation can be done solely by manipulating the entangled pair without transmitting anything else. It deserves more attention I think
"YES, WE GOT IT! We can now transfer people to locations faster than li-" The universe: woah woah woah, slow down there buddy, not so fast. You won't get away with this, fuck you!
Imagine a guy has a closed box and asks "Is there a cat in here?" and you say "Maybe?" and then the guy never opens the box. congrats now you're up to speed.
ehhh its a bit easier to imagine this: While blind folded, you push an object onto the floor. There is no sound, and you do not know if it is broken or not. The whole idea is that until you check to see if its broken, it is in a superposition state of being both broken and not broken. When you take off the blindfold, the universe kinda makes up its mind and decides on whether it is broken, or its not broken.
Example. you drop your phone, is the screen cracked or not. how do you find out. you look, thus collapsing the states of the screen to broken or not. hearing the screen break would be an observation causing the same results as picking it up to look does
Potato The Turnip How does it depend on weather I check it or not? like is not it already broken when I pick it? I mean that sounds like a magic like phone is not broken but when i pick it up it becomes broken?
MinezGio Not exactly. Superposition in quantum physics is a state that is completely separated from our intuitive understanding of the world around us. Imagine that: A blind man is trying to figure out the position of a candle that is somewhere located in his room. The only help he's got is a ball he can throw at the candle to tell by the sound where exactly that candle is located. However, the moment he finds out, the position of the candle has changed because he threw a ball at it. The moment we try and meassure the state of a quantum particle, it takes a certain position, even though it behaved as if it had multiple positions before we observed it.
I think this is the only channel where "flea", "moon" and "quantum superposition" can be placed in the same sentence in a way that seems totally normal
This is why it's very important to have a sound proof box.... Or a mute (eh, non-verbal? Non-communicative?? Oh no, I don't know the right term to use... Please don't cancel me!) cat.
using coins is ideal IMO. heads and tails are easy to keep straight, but are still macro objects, and won't make people feel like they need any understanding of quarks.
I agree but not sure it would have had as big of an audience and a lot of people who aren't versed in physics may have been less inclined to follow. But yeah, I got confused by this at points and had to stop the video and check what he'd said but wouldn't (well, probably wouldn't) have had to had it been about elementaries in the first place.
Imagine all life as you know it ceasing as every molecule in your body is painfully erased. Meanwhile, thousands of miles away, an exact clone of you with all of your memories goes "Wow, I successfully teleported! And it was completely painless too!" That was always my biggest fear of teleportation.
Yeah, and even though in the video he says it isn't cloning, the teleportation of this video seems to be one of those, where the original is destroyed/transformed.
*Your consciousness teleports as well. That clone shit is ridiculous. I’ve already seen my neighbour teleport twice, but she’s playing dumb. She knows I saw her do it too. She’s still the same person - no clone.*
After he said “If only we had some way to get there faster...” I genuinely thought he was gonna continue with “...Speaking about that, let’s talk time travel now !!”
I honestly think you're complicating it. What's wrong with using particles? I think that would be easier to comprehend than cats and fleas. People with no background in this will only be confused and lose track.
huh strange. I didn't realize I lived near a super massive black hole causing what was a minute to MinutePhysics to become 14 minutes and 12 seconds to me...
Shouldnt MinutePhysics live close to the black hole? When near a black hole, time slows down, so that when 1 minutes passes there, somewhere else further away 14 minutes pass.
One question that I want to know, which this video doesn't explain: What happens to the cat itself? Like yeah, okay, the cat got teleported, but what about it's conscious? Imagine the cat as a human for a second, that'll make this easier. You, as a human, can think, remember stuff, have a conscious, identity, all that. So... if say, you got teleported, what would happen to *YOU?* would you remember what happened before you were teleported and stuff, and it would seem like it does in movies, where you were on the earth and a little bit later on the moon suddenly? Or would you just die, and the you that's now on the moon be completely separate, as if you were born exactly like that with all the memories and everything? Does that make sense? Like yeah, your physical existence is teleported, but is YOU YOURSELF teleported? I don't really know how else to explain it honestly, so I hope that makes sense.
the thing about explaining this sort of science is it doesn't really matter what words you use; so if it matters to you .. then you might want to think about your strategy for understanding science.
There is nothing "easy" about quantum mechanics. Even the most renowned scientists admit they don't fully understand what the fuck is going on in that domain.
akshay rathore I agree, especially because it implies to the layman that you can kill a flea on the moon by telling an astronaut whether a cat is dead or alive.
in 2020, i watched this video and was fascinated, even though i didn't understand much. two years and a lot of research later, i'm studying to get into uni to study physics. this video was one of my wake up calls. thank you so much for that.
I have a very strong suspicion that this could have been explained much simpler. And not in a Deloren transporting you back to 1955 kind of way, either.
Year 2118: First successful teleporting of a human expirement Also year 2118, same experiment: the human collapsed in a superposition, expirement failed
Yes, it is an explanation in minutes and relatively short for something that could have taken an hour to thoroughly explain. What’s your point? He successfully communicated to a broad audience without making it either too detailed or too watered down, so that people could readily connect, get the general idea, and themselves look up further details. That’s a successful video, esp. considering the otherwise generally content-void rubbish on UA-cam like ‘life pranks’, ‘beauty channels’, gossip… about other UA-camrs, the bazillion Minecraft let’s‚ plays, the idiots who spend way too much time over interpretting trailers or mere teasers of the next Game of Thrones season, etc.
+reelle Zahl I think this was supposed to be a joke. If you read GladiatorGator's comment he also said (Jk if anyone thinks I'm dum) So Augustus probably made a joke about the word "dum"
Oh, wow... I thought I understood quantum entanglement with the coins on different sides of the universe, but the gunpower and cat analogy explains it a lot more. Thanks!
I appreciate the closed captions very much. Even though I'm not deaf, it still helps (and makes me cheer in happiness because having captions means more accessibility!)
I know you are using the cat to explain complex ideas in an understandable way. But believe me, this just makes it worse. Using the word ”cat” instead of electron or photon and the words ”dead” and ”alive” instead of spin down and spin up, makes it even more difficult to understand.

I know im a bit late to this but i can't help but point a few things out. 1. When you mentioned what would happen to the original "CAT" once it was teleported you said it would be in a superposition with every possible three letter configuration but i don't see how that is possible since the original "CAT" was made up of the three letters c,a,t and in order to have any configuration of letters that contained letters beside c,a,t that would imply the teleportation process would have created new matter which is impossible since we know that matter cannot be created nor destroyed only change form. What would actually happen is the original "CAT" would enter a superposition of every possible configuration of those three letters c,a,t. 2. This would imply there is a chance the original "CAT" would remain in its original configuration even if the chance of that happening is extremely low, which would mean there is a very low chance that after the original "CAT" has been "teleported" by reconfiguring matter somewhere else to reform into the "CAT", the original could end up not changing at all as if nothing had happened while the teleported version forms essentially creating an exact copy in other words a clone which earlier in the video you stated is impossible. 3. There fore either it is possible to clone using this method or the method is impossible to begin with and this doesn't even take into consideration the moral and or philosophical implications created by using this method. 4. This entire method is not necessary because using wormholes we can just connect two points in spacetime allowing for instant travel in other words teleportation as theorized by Einsteins theory of general relativity rendering this entire process redundant to begin with. If i missed any thing or am wrong about something please correct me but as far as i know everything i have stated above is correct.
Xi H Then put a cat in a blender if you cant imagine it. trust me there is nothing like a cat screaming in pain trying to break out of a blender and you hold down the lid and watch with a raging boner as it is. screeching as it dies a painful horrible death. makes you feel alive
What I don't get: 4:05 to teleport the cat to the moon, we need to get it entangled. To entangle it we need to get something already entangled on the moon. That's almost a catch 22. If I'm not mistaken, this means it's impossible to teleport somewhere we haven't been before. So we could never teleport somewhere really far away, like a neighboring Galaxy unless we went there first. Meaning we'd have to send a bunch of well-trained astronaut volunteers unrelated to another to that said Galaxy, and have them breed in space and raise/train their kids (and hope they catch on and are willing to accept their new lives and understand it's importance) and repeat that cycle until they reach the galaxy to make the observation to teleport whatever it is that will allow them to start setting up the new civilization. Oh, and the entire time, nobody can know what's in the "box" (or state of, w.e.) or else it will all be for nothing.
It is good that you concluded that this is a teleport of properties, not objects, which will never be possible unless there is a prefabricated superposition in the target. But Schrodinger's cat, as mentioned at the beginning, is exactly how it can never work in the macro world, which Schrodinger pointed out by his model cat.
Wow. What an accurate and fun way of explaining Quantum teleportation and switching to Bell basis and performing a Bell measurement! wow! You deserve a science communication award (if one exists) for just this video. Also loved the state with a big tombstone (dead cat) and a little tombstone (dead flea). funny!
Yessss! I do this too! I do not believe in a pack of playing cards that the order of which the playing cards are sitting in is final before you have picked one up and looked at it. You might aswell assume that every card is blank and then decideds what its going to be once you pick it up and look at it. I do believe in a sense that you can jinx something. I feel like maybe the card could have been maybe a 5 but because you asked "please be a 5, please be a 5", its going to decide well since you wanted me to be a 5 and were so demanding, im going to change myself to a 7 or what have you. 😂 so I try to keep my mind as blank as much as possible like when I want something specific like in a game or even a scratchy ticket or the odd time I have played on the pokies. Well im not a very lucky person so im not sure my blank mind thinking is working 😂.
The problem with this is that the order is predetermined. The cards were put in a certain order in the box. With the cat, it’s a hypothetical thought experiment where there is no possible way to know whether it’s dead or alive.
Ah but say that the deck was somehow completely randomized, with no way of knowing the starting conditions, and remained unobserved until opened. Then would each card be a superposition of all possible 52 cards?
Crazy3lf He's done that already. To ELI5, slowing down time is really easy, speeding up time is really easy, and going backwards is really, really, REALLY hard.
One point I would like to emphasize is that you have to transmit some kind of classical information (here the result of the indirect measurement). And that is what prohibits any kind of faster than light communication.
Plasmaboo I wouldn't go as far as saying that it completely ruins the point of teleportation. Sure, it doesn't correspond to what we commonly picture as teleportation, such as an instant travel mechanism. However this method here may be the only sort of thing to make lightspeed travel actually possible, which in itself is actually an incredible achievement opening huge possibilities (that will, alas, most likely always remain in the domain of sci-fi when it comes to transporting actual people...).
To be useful, it hasn't got to be able to transmit information faster than light. It makes copying the state of a quantum object possible, which can't be measured at all. (cause the moment it is measured, it collapses into one of two states, but there's no way to get the probabilities of each state, which is what quantum computers use for calculation)
So what if we can't do faster than light? We still would be able to transmit matter at significant fractions of it thanks to communications tech. Imagine no more rockets blasting off from the surface of the planet to space, and instead they just get teleported into space directly.
I find it hard to focus on what's going on when all I can think about is how Schroedinger's Cat was his way of mocking the whole "it's in everywhere/in every state until we observe it" concept of quantum mechanics. No, it isn't actually in every state it's in one state, you just don't know which it is until you observe it.
I can just imagine stepping onto a teleporter to teleport to Mars, waiting a couple minutes and suddenly exploding while simultaneously instantly assembling on mars.
Unless the universe is a computer program, and there are many version of that same program but on different forms of hardware, parallel universes probably don't exist.
I would understand this astronomically more with particles. The cat and flees feels like a crazy indirect way of explaining that I have to try to imagine how it was supposed to be analogous to particle behaviour
This could have important implications for how we deal with long term sea level rise Imagine if it was possible to simply entangle some particles on the iceberg, send one of those particles to an asteroid, and pull the lever. An asteroid doesn't flood a city.
Just watching without understanding a single thing I thought: Hopefully I´m near the end, because it´s getting supercomplicated. ---Loking at the time: 4:30 Oh no, I´m out here.
@@jacobdittmer5512 No, this was never an analogy meant to explain superposition. Schrodinger created as a tool to demonstrate how absurd the concept of the superposition is.
*Mom knocks and comes in* "Jimmy, why exactly did you put Mr. Mittens in a box along with a box of flees?" "Science, mom. Science." *Later that evening* "NASA scientiest found a box of flees hidden on a lunar module just minutes before launch. Their origin is still unknown."
You said no cloning when teleporting with quantum theory, but in one of your example, in teleporting the word "CAT" there is a very small chance that the word on the earth will stay the same as "CAT" from the superposition probability of all 3 character words. Isn't that now cloning?
That chance is exactly the same as the chance that the letters on the moon had spelled "CAT" in the first place. So in that case, it's not cloning, it's just that nothing really happened.
You couldn't infer (without cheating somehow) that the original data was CAT and not DOG, or FXM, or AAA, or HAM, or... so the information is lost. Does that help?
It's not cloning because the original isn't in *one of the possible* states, it's in a superposition of *all the possible states*. So it's not that there's "some probability of it spelling CAT", it's that it's spelling all the words at once, which is...well, very different from the word "CAT" :D
IceMetalPunk I guess he means if you look at that after all the process, the collapse of the three letter system could end up being CAT again, just by chance, since there's an equal probability that it will collapse in either of the combinations. But as someone already pointed out, I guess the information about what that three letters were at the beginning is lost.
What happens to the cat's consciousness? Would it lose its memory and act like an entirely new being, totally brain dead void of its original self, just a physical shell? Or would it be the exact same cat on every level? Would it remember going through the teleporter and its life beforehand and still perceive the universe the exact same way as before?
What if the soul exists on a parallel plane and is entangled with our physical existence on this plane? Does the technology we have also account for the entanglement of the soul, or did we not factor for it?? Now if we were teleporting a robot cat, we would not have to worry. The programming state should also be transferred.
I don't think the question is about 'the soul' as what is 'the soul'? People are made up of chemicals fundamentally, lots and lots of different substances and so when you break down and reassemble the brain at a molecular level, including the molecules which account for memory and even personality, would they reform totally blank on the other side? Wiped of all data stored by the previous body? If you were transporting a robot cat then wouldn't you have to backup the data before disassembling and reassembling it at a molecular level? The physical being is identical however the information stored within the being is not part of that disassembly and reassembly process as it is just information, code, it isn't physical so shouldn't that be totally erased? With the physical being ending up a vegetable on the other side?
Isn't data stored also just a state of being? And isn't the method of teleportation stated by the video just a transference of the state of the molecules from one location to another? The video even states at the end that after molecular state is teleported to Location B, the molecular state at Location A becomes jumbled (12:37). This is further backed up by the word "CAT" teleportation [Before: |CAT> After: |AAA>+|AAB>+....|ZZZ>] (12:56 ). Ergo, if state=being, and being=soul, the state of existence is literally transferred. As we will assume that the total current state of the molecules was transferred (speed of molecules or heat, molecular bonds, etc.), we can assume that the state of existence or the soul is also transferred. This is, however, if the absolute current state is transferred, which is complicated more by the number of particles that are involved in the teleportation. The more number of particles involved, the more particle states we have to account/compute for. It's like going from equations of one variable to equations of n variables. The computation definitely becomes more complex, but as long as we can compute for half of variables involved, we will be able to secure teh state of the other half.
thewatcherinthecloud I understand where you're coming from in terms of a robot cat as in robotics data is a physical change (didn't know this previously), but consciousness is different and so is the memory in a being, so I understand how teleportation could recreate a physical body perfectly, but when deconstructing a chemical memory like in the brain would the data be lost or would it survive?
TheFlyingMonkey200 the "how" depends on the situation, but it happens when the state of one particle depends on the state of another. for example: in the orbital of an atom, there can be 2 electrons with the condition that one of them has the opposite spin of the other, so, if we measure the spin of one of them and it is positive, we don't even need to measure the other one to know it will be negative, so we say that their states are entangled
Particles become entangled by interacting with each other. They do this by affecting and reacting to the energy of a field, which itself, can also become entangled with particles, other fields and... itself, i guess?
They do the dirty dancing... nobody puts particle baby in a corner. Sounds like a lot of theoretical nonsense to me, but I am just on here looking for funny cat videos... or I'm not ;) Fun Fact Schrodinger didn't even believe in Schrodinger's cat theory
Particles become entangled when the state of one particle can be determined by the state of another particle. Here's an easy example, say you ordered a chicken sandwich and a hamburger. You got them and they both came in separate boxes, but you don't know which box contains which sandwich. Once you open one box, you know what the other contains. And this is true no matter how far apart those boxes are. This is kind of like when particles are entangled: when knowing the state of one, you can figure out the state of another.
This is what's so ridiculous about it, measuring spin of particles or looking in boxes doesn't do ANYTHING to the other box. It doesn't "force nature to decide." It just tells you what it is. Superposition is just the observer's lack of knowledge of the states.
I've always thought we could eliminate internet RTT (ping) using quantum entanglement. It'd be amazing for real-time applications like voice chat, video chat, and games. It'd be a game-changer if it ever came to fruition.
sorry isnt physically possible. lets say you send a package on information that way. you can teleport a state by asking a question on one side of the entanglement and the person receives the answer to that question on the other side. But they cant do anything with that answer if they dont know the question they received an answer to, so you have to send the question to them with normal slower than light communication
@@botboy0 yes the problem is that you have to manually set the stage of one part of the quantum entanglement so that the other part is the exact eopposite of that what you wanted. But it is random if you look at it so the other part do not know what you wanted to choose so there is no transfer of informarion.
This only considers the quantum part of this. What I think of is since you can’t really use binary code one would have rewrite computer code from the ground up with all new abstraction levels before we could get the the same level of usability. Just think how long it taken us to get to our current level with binary. Just a thought to consider. Sure the transmission lag might be cut out but the processing of the signal itself is a challenge in and of itself.
I enjoyed the video, an interesting concept for certain although I would like to mention that the analogies/metaphors with the cat and flea were a bit confusing and overcomplicated the concept in my mind. I feel like I would've been able to understand it easier if you used particles themselves as the examples instead of the flea and cat, I got a little lost with all the "alive dead cat flea earth moon" being used so often in close proximity to each other. Thank you though, it is quite fascinating regardless of how it was explained.
The teleportation part was that you bring a box which might have an alive flea (or jumble of particles) in it to the moon and put the other box which has been entangled with another maybe alive flea (or jumble of particles) into a box with a cat. Then by indirectly measuring the box with cat and flea you transfer the alive/dead state of the cat to the flea on the moon (or convert the jumble of particles on the moon to a cat). The process ends up jumbling the state of the cat on earth. In the jumble of particles scenario, you bring a box of particles to the moon, and when the indirect measurement happens and the information is sent to the moon, you end up with a cat on the moon instead of a jumble of particles and a jumble of particles on the earth instead of the cat. Aka the cat has been teleported from earth to moon via the boxes of particles
But you had to put it in the box in the first place, so if you opened it early you would get the exact same result. But that would make sense, and they would not get grants to study it.
If you open the box, you basically remove the entanglement and the cat's state can't be transferred into the jumble of particles on the moon. The point is that you're not putting the cat in the box that you bring to the moon
This is incredibly simplified (and probably wrong because I am not a quantum physicist) but to use the cup trick analogy: - you have two cups with same things in them, cups one and two - you take cup two to the moon - you get a third cup with a cat, cup three - you put cup one in cup three - you x-ray cup three with cup one in it (so you don't know everything about the contents, but just enough to make the trick work) - you tell the girl on the moon something about what is inside - she tweaks a setting on her machine and now the cat is inside cup two on the moon - cup three no longer contains a cat, only the bits that the cat was once made from note that the cat was not in the first two cups, and was not sent to the moon until the trick takes place
13:07 if after teleportation cat will be in every possible combination of three letter words, each one equally likely then isn't there a chance that it can be again "cat" ? (very little probability though)
I mean, I suppose it'd be possible you end up with a rat and some leftover goop if you teleported a cat... Although the "furthest possible away" part might prohibit the formation of structures like that since any mammal is very similar to any other mammal when it comes to layout. What's the most different possible letter to "C"?
That was a very very accurate explanation of how quantum teleportation works! Even with the "questions" analogy. Bien jugado, Henry.

MinezGio Not exactly. Superposition in quantum physics is a state that is completely separated from our intuitive understanding of the world around us. Imagine that: A blind man is trying to figure out the position of a candle that is somewhere located in his room. The only help he's got is a ball he can throw at the candle to tell by the sound where exactly that candle is located. However, the moment he finds out, the position of the candle has changed because he threw a ball at it. The moment we try and meassure the state of a quantum particle, it takes a certain position, even though it behaved as if it had multiple positions before we observed it.

am I the only one who thinks that using quarks instead of cats and fleas would've been simpler?
Yes.
nah i agree. using macro-scale objects as an analogy for energy fields is confusing for me as well
using coins is ideal IMO. heads and tails are easy to keep straight, but are still macro objects, and won't make people feel like they need any understanding of quarks.
I agree but not sure it would have had as big of an audience and a lot of people who aren't versed in physics may have been less inclined to follow.
But yeah, I got confused by this at points and had to stop the video and check what he'd said but wouldn't (well, probably wouldn't) have had to had it been about elementaries in the first place.
Quarks can't exist in isolation, so no that wouldn't be simpler.

Imagine all life as you know it ceasing as every molecule in your body is painfully erased. Meanwhile, thousands of miles away, an exact clone of you with all of your memories goes "Wow, I successfully teleported! And it was completely painless too!" That was always my biggest fear of teleportation.
Yeah, and even though in the video he says it isn't cloning, the teleportation of this video seems to be one of those, where the original is destroyed/transformed.
Well then you will have to define if a jump in the stream of consciousness cause the consciousness to be no longer the same

Good.
One question that I want to know, which this video doesn't explain: What happens to the cat itself? Like yeah, okay, the cat got teleported, but what about it's conscious? Imagine the cat as a human for a second, that'll make this easier. You, as a human, can think, remember stuff, have a conscious, identity, all that. So... if say, you got teleported, what would happen to *YOU?* would you remember what happened before you were teleported and stuff, and it would seem like it does in movies, where you were on the earth and a little bit later on the moon suddenly? Or would you just die, and the you that's now on the moon be completely separate, as if you were born exactly like that with all the memories and everything? Does that make sense? Like yeah, your physical existence is teleported, but is YOU YOURSELF teleported? I don't really know how else to explain it honestly, so I hope that makes sense.

The real challenge is to think inside the box
When *minute physics* needs 14 minutes to explain teleportation only on a theory level...
Yes, it is an explanation in minutes and relatively short for something that could have taken an hour to thoroughly explain. What’s your point? He successfully communicated to a broad audience without making it either too detailed or too watered down, so that people could readily connect, get the general idea, and themselves look up further details. That’s a successful video, esp. considering the otherwise generally content-void rubbish on UA-cam like ‘life pranks’, ‘beauty channels’, gossip… about other UA-camrs, the bazillion Minecraft let’s‚ plays, the idiots who spend way too much time over interpretting trailers or mere teasers of the next Game of Thrones season, etc.

I know im a bit late to this but i can't help but point a few things out.
1. When you mentioned what would happen to the original "CAT" once it was teleported you said it would be in a superposition with every possible three letter configuration but i don't see how that is possible since the original "CAT" was made up of the three letters c,a,t and in order to have any configuration of letters that contained letters beside c,a,t that would imply the teleportation process would have created new matter which is impossible since we know that matter cannot be created nor destroyed only change form. What would actually happen is the original "CAT" would enter a superposition of every possible configuration of those three letters c,a,t.
2. This would imply there is a chance the original "CAT" would remain in its original configuration even if the chance of that happening is extremely low, which would mean there is a very low chance that after the original "CAT" has been "teleported" by reconfiguring matter somewhere else to reform into the "CAT", the original could end up not changing at all as if nothing had happened while the teleported version forms essentially creating an exact copy in other words a clone which earlier in the video you stated is impossible.
3. There fore either it is possible to clone using this method or the method is impossible to begin with and this doesn't even take into consideration the moral and or philosophical implications created by using this method.
4. This entire method is not necessary because using wormholes we can just connect two points in spacetime allowing for instant travel in other words teleportation as theorized by Einsteins theory of general relativity rendering this entire process redundant to begin with.
If i missed any thing or am wrong about something please correct me but as far as i know everything i have stated above is correct.

What I don't get:
4:05 to teleport the cat to the moon, we need to get it entangled. To entangle it we need to get something already entangled on the moon. That's almost a catch 22. If I'm not mistaken, this means it's impossible to teleport somewhere we haven't been before. So we could never teleport somewhere really far away, like a neighboring Galaxy unless we went there first. Meaning we'd have to send a bunch of well-trained astronaut volunteers unrelated to another to that said Galaxy, and have them breed in space and raise/train their kids (and hope they catch on and are willing to accept their new lives and understand it's importance) and repeat that cycle until they reach the galaxy to make the observation to teleport whatever it is that will allow them to start setting up the new civilization. Oh, and the entire time, nobody can know what's in the "box" (or state of, w.e.) or else it will all be for nothing.

This feels like algebra, but instead of messing with numbers you're messing with particles. Feels..odd, but its really cool that this actually works!!
It is good that you concluded that this is a teleport of properties, not objects, which will never be possible unless there is a prefabricated superposition in the target. But Schrodinger's cat, as mentioned at the beginning, is exactly how it can never work in the macro world, which Schrodinger pointed out by his model cat.
Wow. What an accurate and fun way of explaining Quantum teleportation and switching to Bell basis and performing a Bell measurement! wow! You deserve a science communication award (if one exists) for just this video.

When I was younge I would think my tazos/Pokemon cards would change throughout all the possibilities until I opened them and broke the bond...

Shrödinger's pokémons.
Yessss! I do this too! I do not believe in a pack of playing cards that the order of which the playing cards are sitting in is final before you have picked one up and looked at it. You might aswell assume that every card is blank and then decideds what its going to be once you pick it up and look at it. I do believe in a sense that you can jinx something. I feel like maybe the card could have been maybe a 5 but because you asked "please be a 5, please be a 5", its going to decide well since you wanted me to be a 5 and were so demanding, im going to change myself to a 7 or what have you. 😂 so I try to keep my mind as blank as much as possible like when I want something specific like in a game or even a scratchy ticket or the odd time I have played on the pokies. Well im not a very lucky person so im not sure my blank mind thinking is working 😂.
The problem with this is that the order is predetermined. The cards were put in a certain order in the box. With the cat, it’s a hypothetical thought experiment where there is no possible way to know whether it’s dead or alive.
Ah but say that the deck was somehow completely randomized, with no way of knowing the starting conditions, and remained unobserved until opened. Then would each card be a superposition of all possible 52 cards?

It's basically a big ball of timey wimey.... stuff.
well he did just tease/confirm thats what his next video is gonna be
One point I would like to emphasize is that you have to transmit some kind of classical information (here the result of the indirect measurement). And that is what prohibits any kind of faster than light communication.
excellent point
Plasmaboo I wouldn't go as far as saying that it completely ruins the point of teleportation. Sure, it doesn't correspond to what we commonly picture as teleportation, such as an instant travel mechanism. However this method here may be the only sort of thing to make lightspeed travel actually possible, which in itself is actually an incredible achievement opening huge possibilities (that will, alas, most likely always remain in the domain of sci-fi when it comes to transporting actual people...).
Just quantum teleport the information. Easy.
To be useful, it hasn't got to be able to transmit information faster than light. It makes copying the state of a quantum object possible, which can't be measured at all. (cause the moment it is measured, it collapses into one of two states, but there's no way to get the probabilities of each state, which is what quantum computers use for calculation)
So what if we can't do faster than light? We still would be able to transmit matter at significant fractions of it thanks to communications tech. Imagine no more rockets blasting off from the surface of the planet to space, and instead they just get teleported into space directly.

I find it hard to focus on what's going on when all I can think about is how Schroedinger's Cat was his way of mocking the whole "it's in everywhere/in every state until we observe it" concept of quantum mechanics. No, it isn't actually in every state it's in one state, you just don't know which it is until you observe it.

You said no cloning when teleporting with quantum theory, but in one of your example, in teleporting the word "CAT" there is a very small chance that the word on the earth will stay the same as "CAT" from the superposition probability of all 3 character words. Isn't that now cloning?
That chance is exactly the same as the chance that the letters on the moon had spelled "CAT" in the first place. So in that case, it's not cloning, it's just that nothing really happened.
You couldn't infer (without cheating somehow) that the original data was CAT and not DOG, or FXM, or AAA, or HAM, or... so the information is lost. Does that help?
It's not cloning because the original isn't in *one of the possible* states, it's in a superposition of *all the possible states*. So it's not that there's "some probability of it spelling CAT", it's that it's spelling all the words at once, which is...well, very different from the word "CAT" :D
IceMetalPunk I guess he means if you look at that after all the process, the collapse of the three letter system could end up being CAT again, just by chance, since there's an equal probability that it will collapse in either of the combinations. But as someone already pointed out, I guess the information about what that three letters were at the beginning is lost.
What happens to the cat's consciousness? Would it lose its memory and act like an entirely new being, totally brain dead void of its original self, just a physical shell? Or would it be the exact same cat on every level? Would it remember going through the teleporter and its life beforehand and still perceive the universe the exact same way as before?
What if the soul exists on a parallel plane and is entangled with our physical existence on this plane? Does the technology we have also account for the entanglement of the soul, or did we not factor for it??
Now if we were teleporting a robot cat, we would not have to worry. The programming state should also be transferred.
I don't think the question is about 'the soul' as what is 'the soul'? People are made up of chemicals fundamentally, lots and lots of different substances and so when you break down and reassemble the brain at a molecular level, including the molecules which account for memory and even personality, would they reform totally blank on the other side? Wiped of all data stored by the previous body?
If you were transporting a robot cat then wouldn't you have to backup the data before disassembling and reassembling it at a molecular level? The physical being is identical however the information stored within the being is not part of that disassembly and reassembly process as it is just information, code, it isn't physical so shouldn't that be totally erased? With the physical being ending up a vegetable on the other side?
Isn't data stored also just a state of being? And isn't the method of teleportation stated by the video just a transference of the state of the molecules from one location to another? The video even states at the end that after molecular state is teleported to Location B, the molecular state at Location A becomes jumbled (12:37). This is further backed up by the word "CAT" teleportation [Before: |CAT> After: |AAA>+|AAB>+....|ZZZ>] (12:56 ).
Ergo, if state=being, and being=soul, the state of existence is literally transferred. As we will assume that the total current state of the molecules was transferred (speed of molecules or heat, molecular bonds, etc.), we can assume that the state of existence or the soul is also transferred. This is, however, if the absolute current state is transferred, which is complicated more by the number of particles that are involved in the teleportation. The more number of particles involved, the more particle states we have to account/compute for. It's like going from equations of one variable to equations of n variables. The computation definitely becomes more complex, but as long as we can compute for half of variables involved, we will be able to secure teh state of the other half.
We are made of atoms (or quantums or something) and only the sum of our parts so nothing would be lost
thewatcherinthecloud I understand where you're coming from in terms of a robot cat as in robotics data is a physical change (didn't know this previously), but consciousness is different and so is the memory in a being, so I understand how teleportation could recreate a physical body perfectly, but when deconstructing a chemical memory like in the brain would the data be lost or would it survive?
I have a question that I don't think you answer in the video, correct me if I'm wrong, how do particles become entangled?
TheFlyingMonkey200 the "how" depends on the situation, but it happens when the state of one particle depends on the state of another. for example: in the orbital of an atom, there can be 2 electrons with the condition that one of them has the opposite spin of the other, so, if we measure the spin of one of them and it is positive, we don't even need to measure the other one to know it will be negative, so we say that their states are entangled
Particles become entangled by interacting with each other. They do this by affecting and reacting to the energy of a field, which itself, can also become entangled with particles, other fields and... itself, i guess?
They do the dirty dancing... nobody puts particle baby in a corner. Sounds like a lot of theoretical nonsense to me, but I am just on here looking for funny cat videos... or I'm not ;) Fun Fact Schrodinger didn't even believe in Schrodinger's cat theory
Particles become entangled when the state of one particle can be determined by the state of another particle. Here's an easy example, say you ordered a chicken sandwich and a hamburger. You got them and they both came in separate boxes, but you don't know which box contains which sandwich. Once you open one box, you know what the other contains. And this is true no matter how far apart those boxes are. This is kind of like when particles are entangled: when knowing the state of one, you can figure out the state of another.
This is what's so ridiculous about it, measuring spin of particles or looking in boxes doesn't do ANYTHING to the other box. It doesn't "force nature to decide." It just tells you what it is. Superposition is just the observer's lack of knowledge of the states.
Everybody gangsta until Schrodinger's cat walks in except it doesn't..

this is probs accurate but i forgot my adhd meds soooo,, HEY LOOK A CAT
I've always thought we could eliminate internet RTT (ping) using quantum entanglement. It'd be amazing for real-time applications like voice chat, video chat, and games. It'd be a game-changer if it ever came to fruition.
sorry isnt physically possible. lets say you send a package on information that way. you can teleport a state by asking a question on one side of the entanglement and the person receives the answer to that question on the other side. But they cant do anything with that answer if they dont know the question they received an answer to, so you have to send the question to them with normal slower than light communication
@@botboy0 yes the problem is that you have to manually set the stage of one part of the quantum entanglement so that the other part is the exact eopposite of that what you wanted. But it is random if you look at it so the other part do not know what you wanted to choose so there is no transfer of informarion.
This only considers the quantum part of this. What I think of is since you can’t really use binary code one would have rewrite computer code from the ground up with all new abstraction levels before we could get the the same level of usability. Just think how long it taken us to get to our current level with binary.
Just a thought to consider. Sure the transmission lag might be cut out but the processing of the signal itself is a challenge in and of itself.
I enjoyed the video, an interesting concept for certain although I would like to mention that the analogies/metaphors with the cat and flea were a bit confusing and overcomplicated the concept in my mind. I feel like I would've been able to understand it easier if you used particles themselves as the examples instead of the flea and cat, I got a little lost with all the "alive dead cat flea earth moon" being used so often in close proximity to each other. Thank you though, it is quite fascinating regardless of how it was explained.
Instructions unclear, the moon now has a feline populace at war with dead fleas.
"If only we had some way we could get there... faster."
Sounds like you're holding out on us, Henry.
So if you fly to the moon with a box that might have something in it and mathematically prove it's in the box, that's teleportation?
The teleportation part was that you bring a box which might have an alive flea (or jumble of particles) in it to the moon and put the other box which has been entangled with another maybe alive flea (or jumble of particles) into a box with a cat. Then by indirectly measuring the box with cat and flea you transfer the alive/dead state of the cat to the flea on the moon (or convert the jumble of particles on the moon to a cat). The process ends up jumbling the state of the cat on earth.
In the jumble of particles scenario, you bring a box of particles to the moon, and when the indirect measurement happens and the information is sent to the moon, you end up with a cat on the moon instead of a jumble of particles and a jumble of particles on the earth instead of the cat.
Aka the cat has been teleported from earth to moon via the boxes of particles
But you had to put it in the box in the first place, so if you opened it early you would get the exact same result. But that would make sense, and they would not get grants to study it.
If you open the box, you basically remove the entanglement and the cat's state can't be transferred into the jumble of particles on the moon.
The point is that you're not putting the cat in the box that you bring to the moon
how did you not? all your really doing with this is a cup trick, then sort of looking under one to see if it is there.
This is incredibly simplified (and probably wrong because I am not a quantum physicist) but to use the cup trick analogy:
- you have two cups with same things in them, cups one and two
- you take cup two to the moon
- you get a third cup with a cat, cup three
- you put cup one in cup three
- you x-ray cup three with cup one in it (so you don't know everything about the contents, but just enough to make the trick work)
- you tell the girl on the moon something about what is inside
- she tweaks a setting on her machine and now the cat is inside cup two on the moon
- cup three no longer contains a cat, only the bits that the cat was once made from
note that the cat was not in the first two cups, and was not sent to the moon until the trick takes place

if after teleportation cat will be in every possible combination of three letter words, each one equally likely then isn't there a chance that it can be again "cat" ?
(very little probability though)
yes
No it could be in any possible combination but cat it can never be cat because the particles will try to be as far from a cat as possible
Then can it became a rat
I mean, I suppose it'd be possible you end up with a rat and some leftover goop if you teleported a cat...
Although the "furthest possible away" part might prohibit the formation of structures like that since any mammal is very similar to any other mammal when it comes to layout.
What's the most different possible letter to "C"?
4 years later, it's been teleported into my recommendation list. Time travel works!
