For some time now I wanted to learn and understand quantum computing. so I was happy when Big Think uploaded it. I watched the whole think, very carefully =_=... ...13 minutes later, I still have absolutely no clue what quantum computing is. I hope there will be more videos with Michio Kaku, I like him very much. He's a cool dude.
If you want to learn about quantum computing it is important to start from the basics of computing in general and quantum mechanics, then build your way up into easily understanding how Q-bits implement quantum mechanical reasoning. I suggest you learn the following first (in order): - Bit (Classical bit) - Boolean Algebra. - Computer Logic gates. - Quantum mechanics; starting from the very basics. - Quantum entanglements. You can find highly informative University lectures on topic everywhere on UA-cam. Once you learn only the basics of the topics in the list, you'll quickly make the connection to Quantum computing. Don't worry, it's not AS scary as it looks; though it has its moments ;).
can tell he's super smart cause he's the only guy in these videos that say "we create the coldest space in the universe... *as long as there is no other intelligent life out there like us*" NOBODY ever mentions that! kudos
10-15 million at a good deal sale, and no, the devs have deemed you too greedy because you asked them for 1080p when they weren't ready... In other words, COD is ran by a massive cocktease business.
***** No one explains how they actually work it seem like. What I mean is how do these qubits actually compute anything? You mention branches on probability trees, which is more about this than I've heard anywhere else to date. Where could I learn more about this aspect of how they work? Any suggestions?
This amazing watching the progress of Qcomp < Yes I have coined a word. several years ago there was just so much talk, and now that they have gotten the cooling and other enviro problems reduced IT'S REAL !!!!
Quantum computing would freaking launch our civilization into simply unbelievable levels of advancement, it would be my dream to one day program on one.
How much energy do you have to use in order to get to such low temperatures? Is there a trade off at those low temperatures where you consume more electricity than servers performing the same computations? Where 100 non quantum servers use less electricity than one quantum computer at those low temperatures and perform more 50 times as many computations?
Why? You should rather compete with them, lest they'll become too powerful, and then it's just a matter of time before some greedy short sighted Google majority shareholder group use it to their own benefit at the detriment of everyone else.
so a quantum computer effectively adds a splitter to the 1-0 bits enabling the exploration of all possible values between them? infinitely many decimicles between 0-1 can be explored via quantum computing?
I'm really excited to see what'll happen in the future. Science is moving forward in an accelerated pace. Give it a decade or two, and you'll start seeing quantum laptops and quantum cell phones. If not quantum, it'll be some other technology that surpasses the fastest processors we have today.
Moore's law is already breaking down companies like Microsoft and other computer companies are already stating that it is getting very difficult to update computers and they are rapidly approaching the limit to how to advanced they can be with silicone
@0:11 quote "Quantum mechanics describes how everything in the universe works" But I heard some theoretical physicists say that quantum mechanics still doesn't describe/explain gravity!
What people need to understand is that while quantum computers can calculate much faster than classical computers, it is in the calculation of raw data, not in the calculation of say, a computer game. Quantum computers will not render video and audio much faster than classical computers, but it will preform calculation such as finding the next prime number, much faster.
Does anyone else think if quantum computing was an accesible and feasible thing that'd be out now,the tensions about net neutrality would be rendered moot?
Advanced technology without advanced society with advanced moral values are just too dangerous, just imagine a NSA spying with quantum computing... PS: About the feasibility of this technology itself, I think that before, may be well before, of the quantum computing we will get incredible results earlier with the photonics, just switching from transistors and electrons to photons and optical switches our computers will be faster, lighter and more saving in terms of energy.
Oliver Baker Firstly, I didn't say that I will not use quantum computing or that I shouldn't be researched; I only pointed out that technology alone will not save the day, as the majority of people seems to believe. Secondly, we really don't now at this time even if the quantum computing will ever be possible, so it must be materialized in the everyday life first in order to dwarf anything that is here already.
skater6511 well, theoretically with the quantum computing things that today are pure science fiction would be trivially possible, e.g. they could analyse in real time with very complex artificial intelligence algorithms every single telephone call, e-mail, sms, break any existing (non quantic) cryptographic algorithm; there is, everyone would live in a glass house to them.
baianoise There's no benefit of spying with a quantum computer over a classical computer - there is absolutely no use for "artificial intelligence" implementation in spying either. You seem to be ill informed on the benefits(If any) of quantum computing today's problems.
Cap'n Cook well, really? Because I thought that processing your calculations thousands times faster while spending a fraction of energy would be of some aid...
I don't think, in our lifetime, the two different types of computing will be successfully merged to make that possible. Quantum computing would only work really well for very LARGE computations (with a lot of data, but running the same process on every piece of data). But not tons of different small ones like our computers do these days, which is kind of required for the complex real time simulations that are video games and such.
What really get me: We (human kind) have created all these amazing things based off of math. We say things are true based on proving it with math. This is what blows my mind, Math is a language we created in order to understand the universe, to explain our environment as we perceive it. BUT! math was created for human understanding, it is only as strong as our human minds can comprehend things. What if our comprehension of the universe and things we perceive is completely inaccurate? what if our minds are not able to understand or even comprehend how or why everything is? What if everything we have created works because we have perceived it to work base off of a flawed language? Is math, our most powerful tool, holding us back in big advancements because it is flawed or limited by comprehension? what if there is another language to explain everything? ..... Not trying to sound like a stoner. But I cant help but ponder these things.
+elliott turner All math takes place in an axiomatic system, meaning there are assumptions you make 1st, the axioms- these are fundamentally true in the system - and you must prove everything in the system logically fall out from these axioms. Its not like math is 1 of many possible languages, math encompasses all axiomatic systems. You could say there are hundreds of "languages" or systems in math.
elliott turner Look, the human mind can't comprehend an infinite dimensional object, but we can define it in mathematics. (Don't ask me how, i have absolutely 0 knowledge on this)
+elliott turner thank you all for your reply's I have a bit more understanding now. its amazing what we can do with computing. what took centuries to design and invent can take me a few hours on a CAD program.
mitchell crosby good to see someone else asking those questions. Its amazing how drugs open the doors that our society closes based on observations. My questioning came about in a similar state. I just wonder of the mechanism we developed to understand the universe is actually what is holding us back from comprehension. Or are our human minds just not capable of such feats.
I'm curious as to how much energy is required to create and maintain the rarified environments that enable quantum computing. I have no doubt that such computations may eventually result in much greater universal knowledge and even bring about solutions to many problems we face; however, I question just how big the carbon and fiscal footprints are for such activity. It's not that I'm a die-hard environmentalist. I just always like to make sure the pay-off is worth the cost. Anybody know?
I don't know if creating a true quantum computer will ever be possible, but the most intriguing part about all of this is the consideration of storing an almost unimaginable amount of information on a device with almost unimaginable speed. Then we're talking about simulating universes folks. www.goodreads.com/book/show/18339599-on-computer-simulated-universes?from_search=true
A 64-bit register can store 264 (over 18 quintillion or 1.8×1019) different values. Hence, a processor with 64-bit memory addresses can directly access 264 bytes (=16 exbibytes) of byte-addressable memory.
Xavier oh, I didn't think of it in terms of memory addresses, In that sense Intels 64bit processors are 42bit ...but nevermind, it is just like he said, I was wrong. I got carried away comparing qubits to bits when he was comparing qubits to transistors, describing what 512 qubits could do at theoretical maximum performance, greater than what you actually get out of them, just like many other technologies.
there was an error in previous comment. instead of 264 it should be 2^64. the memory addresses being 64 bit long. and since a bit is either 0 or 1, 2^64 tells the possible number of combinations those bits can be arranged (aka the different possible values) the memory address can have. so 64 bits is 64 bits not 42 bits. so divide 2^64 by 8 and you'll get the number of BYTES for byte addressable memory
I'm sure I read somewhere recently the d-wave quantum computer didnt show any increase in computing power over clasical systems?, and hasnt proved a working quantum machine.
If you didn't have Eric there would have been so much red tape so many blocks in getting these d waves built. Technology in that sense would have been held back.
He said 0 degrees is the lowest possible temperature you can reach in the universe. Shouldn't he know that's impossible to reach (uncertainty principle and all)? I was just surprised he said that.
***** Lol you're full of shit kid. You do realize science is still clueless about how humans can be fully self-aware. Its one of the 15 questions science still cant answer. Stop telling lies bye.
And what would happend if a big ass Underground Earthquake hits this "Cooling Room" for the chips etc? What happens then? What effects will it have on the earth/us?
Let's just talk about something that is iminent. A solarstorm. That would be like an EMP. But Muuuuuch worse. A backup Generator would be useless, all the satalites and all electronic devices would be totally useless. THEN What? :)
Scientists recently revealed that D-Wave's "quantum" computers performed considerably worse than conventional computers - even on tasks that are tailored to give quantum computers an advantage.
MrSquishedsquashed Well, judge for yourself. www.engadget.com/2014/06/20/d-wave-quantum-computer-test-results/ Besides, D-Wave's choice of words was rather juvenile in my opinion.
Quantum computers require incredibly low temperatures to function properly, so I doubt they'll be available to the common person anytime soon, if ever.
I cringed so badly when he kept saying "degrees Kelvin." Seriously? You're building a Quantim Computer. Every Undergrad student this side of the galaxy knows that Kelvin doesn't have "degrees". You don't need a degree (ha!) to know that.
www.theverge.com/2014/6/19/5824336/google-s-quantum-computer-just-flunked-its-first-big-test The technique they're using is and has faced quite a bit of criticism since some believe you don't get the "quantum speedup" that they're speaking of. But lets see how it folds out as more testing and science gets done
It would be funny if after all such effort and quantic computations cientists only get the same answers of good old sense for the problem of the world. We need a new perception of reality.
ENOUGH WITH THE "DIFFICULT TO UNDERSTAND" RHETORIC! Please!!!! Our minds have no difficulty in understanding - only misdirection from being wound up wrong by people looking at it wrong!
Wait, is quantum mechanics really a law and not a theory? Especially since gravity is still a theory, and quantum mechanics cannot fully explain gravity? Or are we supposed to duh our way through this like it's a Supreme Court majority opinion?
You say "theory" like it may or may not exist. The "theory of gravity" may not be correct. We may make observations in the future that lead to changes in the theory of gravity. It doesn't mean that people will start floating off the planet. In the same way quantum particles are observed and the results of the experiments lead to rules that can be applied to theories. Equally, by using some observations it may be possible to calculate something else that **should** be true. Which can then be tested in experiment. (Same goes for evolution btw but let's not go there)
Why are people talking about ifs? quantum computing is possible, there are quantum computers that has done computations.........................................................
The first 5 minutes was interesting then he starts throwing in all this weird terminology, and talks about physics problems which didn't make any sense. Would have been nice to see a photo of the quantum machine working at absolute zero.
Did he really just say at 0:13 that quantum mechanics describes how "everything" in the universe works? WTF LOL what an idiot. Also, at 1:15, he said the lowest possible temperature is absolute zero. LOL Wrong again b/c negative Kelvin actually exists, which is (contrary to the name thus a misnomer) is hotter than anything in the positive kelvin scale b/c objects at negative kelvin have more particles in higher energy states than in the lower energy state (like an inverse pyramid of energy). Reaching negative kelvin doesn't mean we reached absolute zero b/c that would violate the Heisenberg Uncertainty principle, but instead we actually skipped absolute zero. Also, who the hell says "degrees" Kelvin LOL D-wave needs to get a new CEO that knows what he/she's talking about.
The definition of temperature changes when you try to reach "negative temperature." They use different definitions, otherwise it'd be called extremely hot. Edit: Fixed a brain fart.
TboneIsRogue I thought they were using the same definition of temperature that's used to describe positive Kelvin temperatures Luke Brown No, when he was referring to absolute zero, he was talking about it being "the lowest temperature possible in the universe". But yes, I agree that if 0K were to ever be reached, it would theoretically be the point where there would be no interference.
scottseptember1992 Negative temperature is just the energy in reverse. In a sense, the more energy you add to it, the more ordered it becomes. This is the alternate definition from the "average kinetic energy" one.
He is speaking in terms lay-people can understand, according to the average-joe physics framework, nothing he said is wrong. There would be no sense on making a Big Think Talk that no one other than understood people could listen to. Then you could very well download some webimar on the issue if you want College-degree frameworks.
Disclaimer : this is a joke and the the words are organized to produce a sarcastic effect in a funny way > PS: I know that LHC may use the quantum computing for their work , not NSA .
i can only imagine when quantum computers come out to the public, people will be installing windows 13 on it... hopefully by then windows will be cobwebbed and linux has taken over.
PrideTheArrogent A quick look it seems like that's an artifact of the equations. It's a population inversion in energy states. Happens in at least two states in every laser. There are differences from what we usually think of as temperature. For instance if you mix equal amounts of material of a positive and negative temperature (as defined this way) material you end up with infinite temperature, not zero.
THEMithrandir09 I think at least some of these are used to crack encryption keys. Parallel work is one field where quantum computers are vastly superiour.

Intel doesn't call their 64-bit chips, billion-bit.

so you can become economically immortal via quantum computing?
I'm just waiting for it to say 42
solar powered computers
He looks like God !
I'm a programmer
Degrees Kelvin.... C'mon man.
Wait, is quantum mechanics really a law and not a theory? Especially since gravity is still a theory, and quantum mechanics cannot fully explain gravity? Or are we supposed to duh our way through this like it's a Supreme Court majority opinion?
Quantum mechanical laws are derived from the quantum theory, just like the gravitational laws are derived from the theory of gravity.
You say "theory" like it may or may not exist. The "theory of gravity" may not be correct. We may make observations in the future that lead to changes in the theory of gravity. It doesn't mean that people will start floating off the planet.
In the same way quantum particles are observed and the results of the experiments lead to rules that can be applied to theories. Equally, by using some observations it may be possible to calculate something else that **should** be true. Which can then be tested in experiment.
(Same goes for evolution btw but let's not go there)
Non-Abelian Anyon
Why are people talking about ifs? quantum computing is possible, there are quantum computers that has done computations.........................................................
The first 5 minutes was interesting then he starts throwing in all this weird terminology, and talks about physics problems which didn't make any sense. Would have been nice to see a photo of the quantum machine working at absolute zero.
or gaming over 60 fps.
I want Michio Kaku not some crazy geezer :P
Dark matter is easier for q waves computing.
Did he really just say at 0:13 that quantum mechanics describes how "everything" in the universe works? WTF LOL what an idiot. Also, at 1:15, he said the lowest possible temperature is absolute zero. LOL Wrong again b/c negative Kelvin actually exists, which is (contrary to the name thus a misnomer) is hotter than anything in the positive kelvin scale b/c objects at negative kelvin have more particles in higher energy states than in the lower energy state (like an inverse pyramid of energy). Reaching negative kelvin doesn't mean we reached absolute zero b/c that would violate the Heisenberg Uncertainty principle, but instead we actually skipped absolute zero. Also, who the hell says "degrees" Kelvin LOL D-wave needs to get a new CEO that knows what he/she's talking about.
The definition of temperature changes when you try to reach "negative temperature." They use different definitions, otherwise it'd be called extremely hot.
Edit: Fixed a brain fart.
TboneIsRogue I thought they were using the same definition of temperature that's used to describe positive Kelvin temperatures
Luke Brown No, when he was referring to absolute zero, he was talking about it being "the lowest temperature possible in the universe". But yes, I agree that if 0K were to ever be reached, it would theoretically be the point where there would be no interference.
scottseptember1992 Negative temperature is just the energy in reverse. In a sense, the more energy you add to it, the more ordered it becomes. This is the alternate definition from the "average kinetic energy" one.
TboneIsRogue Oh neat thanks!
He is speaking in terms lay-people can understand, according to the average-joe physics framework, nothing he said is wrong. There would be no sense on making a Big Think Talk that no one other than understood people could listen to. Then you could very well download some webimar on the issue if you want College-degree frameworks.
So in a way, using quantum computers, is like segregating and categorizing chances lol
complicated computations for large amount of data , ??? .. hmm < I wonder who has an large amount of data to compute ??? maybe NSA ??? or ...??
Disclaimer : this is a joke and the the words are organized to produce a sarcastic effect in a funny way >
PS: I know that LHC may use the quantum computing for their work , not NSA .
i can only imagine when quantum computers come out to the public, people will be installing windows 13 on it...
hopefully by then windows will be cobwebbed and linux has taken over.
Absolute 0 is imposible to achieve based on Universal laws.

A quick look it seems like that's an artifact of the equations. It's a population inversion in energy states. Happens in at least two states in every laser. There are differences from what we usually think of as temperature. For instance if you mix equal amounts of material of a positive and negative temperature (as defined this way) material you end up with infinite temperature, not zero.
Someone call hacks..
Temp below zero are impossible dude as of ne
Too bad we're never going to see it because of corporatism
d-wave is waaaaaaaaaaaay overhyped and definitely not worth the price tag...but props to their marketing to sucking in buyers :D
101
...except you don't do it linearly.
building Quantum Computers for cancer research? same old bullshit
he still is extremely vague about the facts o.O
Because if he wasn't vague the layman would have no clue what he's talking about.
maybe but it would be interesting to hear who their customers are and what they are already using the systems for
THEMithrandir09
I think at least some of these are used to crack encryption keys. Parallel work is one field where quantum computers are vastly superiour.
The man is a CEO and talks like he wants me to feel sorry for him.. talk about monotone..
His facial hair is a Pokeball...
damn so like computer are bi-sexual?
