The Quantum Internet | Stephanie Wehner | TEDxVienna
Вставка
- Опубліковано 10 чер 2024
- The goal of a quantum internet is to connect quantum processors using long distance quantum communication.
The internet has had a revolutionary impact on our world. The long-term vision of this talk is to build a matching quantum internet that will operate in parallel to the internet we have today. This quantum internet will enable long-range quantum communication in order to achieve unparalleled capabilities that are provably impossible using only classical means.
Stephanie starts by exploring what a quantum internet is good for, and gives an intuition why quantum communication is so powerful. She proceeds from the state of the art today, towards stages for a full blown quantum internet. As an example, she discusses the efforts of the EU quantum internet alliance including the planned demonstration network connecting four Dutch cities in 2020. Stephanie Wehner is an Antoni van Leeuwenhoek Professor at QuTech, Delft University of Technology, where she leads the Quantum Internet efforts. Her passion is the theory of quantum information in all its facets, and she has written numerous scientific articles in both physics and computer science. In a former life, she worked as a professional hacker in industry. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.

Fascinating! Thank you Ms. Wehner.
Who's watching this in 2020? And would now like to see this demonstration of the Quantum Repeater or Teleportation.
TRIPPLE JAY we're getting this quantum internet very very soon.
@@editingreality4779 meh, in about 10 or 20 years.
I showed this to my Entalgled particles
a very lucid, direct, and well-presented explanation. thank you.
Good information shared.Loved it!
That was great. Thank you!
Although my background is in Computer Science but this presentation is very interesting and spiked my interest in Quantum Internet! Thank you for this wonderful presentation!
this is very informative video, I enjoyed watching, thanks for sharing.
Impressive and very informative video. Thanks for sharing it.
Great
Seeing this video in 2020 and pride to say that i read an article saying that new record of distance is made on sending the cubits from one place to another.
An elegant speaker on complex topic.
tedx are always cool.superb theory
Wooo amazing theory. It's really valuable
very nice video..thanks for sharing...
Nice video, thank you.

Great video.. thanks for sharing
Very great video.
Interessant!
good video. very helpful .
Thank you Ms💛
The video is really interesting and informative.Thanks.
really this is very impressive and informative video for us. so many thanks this viodeo
Some people are getting bored because she is smart and the topic is super exciting for scientists and BIG BRAINS.
Great video..
Great Video
This lady has some remarkable presentation skills. It made my day thank you
It's 2021. What's in the box, Stephanie? What's in the box!
exclusive video!
for people that are confused: in simple terms: entanglement is useful for one thing really, very expensive security, you have to entangle to particles and then have to machines that are capable of measuring their states, you then seperate them and to verify communication you use them as keys, the states have to be exactly the same for you to get permission to access which is only possible with the two entangled particles, no other particles can become entangled with them. What this does not do is allow you to communicate using entanglement, particle states are random and cannot be change by humans meaning even if to particles are entangled and on seperate sides of the galaxy it means nothing because we cant actually do anything with them.
Wow!
That was a fantastic message by Stephanie Wehner on Quantum interning. Even a lay man like me could understand it. Thank you very much . William Jayaraj.
Interesting
Freut mich, meine Cousine zu sehen. 👍👍
Hey there buddy, extremely good stream that you have here. I subscribed.
damn mind boggling
Very interesting and funny video, thank you !
B.E.E. building earth ecofriendly
Appreciate the information
You can’t build earth
Waar gaat dit over?
How can I learn more about this?
WoW..She is cool
Maybe there is intergalactic internet between intelligent beings...I hope.
That is a REALLY cool idea that would make an awesome sci-fi.
i concurr
Easy there pal..
They might have it in their brains or whatever they use without any technology
We're getting this quantum internet. Very very soon. And it will be used firstly to receive disclosure.
Highly doubt that this will trickle down to the avarage Joe. How will NSA track my communication?
How about Bluetooth and WiFi ? Will they still work for quantum Internet?
It won't work the same
Great talk,but the long pauses are giving me anxiety.
How would distributed quantum computing look like?
Maybe i'm not getting something, but what is to stop someone from entangling their own quantum repeater with your quantum repeater in essence "tapping the line"? If one entangles one particle with another and then someone else entangles with any of the first two particles then someone else would be able to monitor information in ones "quantum communications". Just a thought..
My understanding is there are a few different quantum cryptographic algorithms but basically you cannot guess the random polarization of each photon bit correctly and because observation of the photon changes its state, a man in the middle attack can always be detected. That is what is so great about quantum cryptography.
you cannot entangle more than two particles
@@aspenyoung2914 After reading your reply I thought that you were correct in your assertion and that i had simply forgotten, but then i wondered some more and consulted Google about it. I found "multipartite entangled states", which seems to state that more than two particles can be entangled.
So we looked at the data
The Ultimate VPN in other words.
Yup
He
She
china has been sending entangled particles/maintaining entanglement for more than 100km for a while now they have a couple of satellites up their that are entangled to quite some distance
satelliites are vulnerable
believe me, China can entangle all universe
Up their what?
@@user-ll4mz8wq3q They can also do it in water. Chinese Scientists recently found there's a window in the blue/green spectrum in sea water that can act as a medium for split protons, with the implication for secure submarine communication. Satellites can be shot down. But sea water? You can't boil the ocean.
She moves stranger
Are we there yet? :)
I was told there would be time travel
earthwatcher2012 yes or it will be able to look into future to see possible scenarios.
👍👏👏 quantum tooth is invented
I am proud of you kangana ranaout.... 😂❄️🦠🎄

One thing not comely right is when you measure a qbit that is entangled it doesn’t send a single photon to the other to keep the law of quantum entanglement because then it would be subject to entisn special theory of relativity and its maximum speed would be C or light and there have been multiple test done to see the speed of quantum entanglement and there have been indefinite results because of our level of technology but we can tell very well that it travels faster than light making a intergalactic internet like many have said possible. That one reason why we need a general theory of everything so that we can unite the Quantum world and normal world into one set of laws.
the maximum speed IS c. it does not break causality. which is a bummer, i know.
@@RogerValor not with contraction of space. Alcubierre for the win.
Great so use it on robots that you send to Mars for real time video feed and controls. Since its instant and solves the speed of light limitations. You dont send anything, Split the entanglement bits between 2 computers and send one to Mars, hook it up to local network on Mars.
it does not solve speed of light limitations. you still send a photon, or use any sort of communication to teleport the qubit.
@@RogerValor No No no , you don't send anything over space. You input on entanglement computer 1 into the entangled bits , then you read the output of the entangled bits on entanglement computer 2, then convert that to regular computer communication input. It solves it over vast distances like between Mars and earth.
Not actually real time, maybe a second or two off, since we have to measure the particles that have changed and arrange that into a picture/video.
@@chaoticmasterpiece Computers will need to work faster than that to stream live feed. Practice that on earth
@@DerekFolan not possible, its not possible to change the state of an entagled particle.
Is she Leslie Winkle from The Big Bang Theory ?
if every one in the world agrees to drink a sip of wisky one by one whenever she says quantum at the end of the video every one would have had their bottles finished
Quantum AI = Genius
exactly, it would predict a crime before it would happen, it would stop corruption by default, the world would never be the same... but this has a dark side also lol
@@deepsi181 humans are a crime, they would be destroyed
So the comms are super secured! Yeah!
Unless... quantum repeater.
i lold
So Basically
This Is Tony Starks' Technology
Aka "Iron Shield"
Still waiting on Computers and internet to make life simpler? Another 20 years, maybe? :-)
Nice topic, but these glimpses of audience looking in awe at the presenter is really distracting to be honest. What is this an episode of Voice?
❤z
so what youre saying is we should structure our internet based on lobsters ?
quantum internet will fix the pings and package lost in gaming, it will make me into a rich man because im a pro gamer but i live far away from my destiny Lol
i just want fast cheap internet
You probably also want a secure internet (for purchases, banking etc) a quantum computer can break 256bit encryption that would take billions of years for a normal computer, so we will need quantum cryptography to make the internet secure again.
@@jibcot8541 how to get in quantum computing ?
Peepee poopoo
Too technical for a general audience. Of course most people are fascinated, but TED is about making ideas simple enough for anyone to understand. Scientists, always remember that with great [knowledge] comes great responsibility. Best wishes.
Imagine 0 ping in CS:GO :D
The future of gaming quantum internet
Traverse the entire universe? :-)
"Spooky action at a distance." Einstein was more right than he knew.
But isn't it that data can't travel faster then the speed of light
I do not have a formal education in the matter, but I believe the concept is that entangled particles are the same particle in 2 different locations (idea of superposition). So by doing something to one version of it, it automatically does it to the other version of it.
I wish they would have used a better speaker
‘’A cubit can be zero and one at the same time.’’ A weird world of Quantum mechanics...It just is beyond our comprehensions. That’s it.
I like it when its beyond comprehension
They had to type L O V E

happy to be #33 in the thumbs down section. Lucky #
I'll use quantum internet hahah
Lol I'm so funny
I find this video useless, even for someone that is trying to understand quantum mechanics in a basic level (like me).
I want to be the first weigh loss program starter program me four Four months of liquid diet then for it to hit me again if I exceed 148 thanks
Send me a blast soon
what is she wearing?
Jon. Ward a Schrödinger outfit. It is fashionable and not at the same time.
She's wearing something and nothing at the same time!
Took her 15min to say somethinh anyone else would in 5...with all the puses and prolonging.... She's not a person you send on TED with limited time for speaking.... Anyone else could have said so much more
This is actually a pretty shallow talk. She drops plenty of names of technical procedures without any actual explanation of what they involve.
Mrdresden I agree, the whole talk could have been delivered in about 5 minutes. I get that English is a secondary language, but, we already have highly encrypted data traffic management capabilities and if they are transporting data across any distances, it will somehow be vulnerable to intercept or “listening“ that makes it vulnerable. I also don’t see the value in a cloud computing oracle that will give you different answers to the same question each time you ask. If a qubit cannot be copied, consistency is problematic and an expensive waste of time. I see quantum computing much more valuable by solving global issues, not replacing the internet. We will probably always need binary computing to manage the qubit inputs and outputs.
The delay in her sentences really bugs me. She over use of stops and
Commas 😠
Everything is secure until it's broken.
How often we see this premise broken?
Next Big Headlines: Two entangled qubits hacked by the ' Quantum' hacker.
And then a new technology comes in promising super security.
Female versi0n of carrot top....lmao
This so called "quantum repeater" thing as presented is a hack, not worthy of serious academic discourse, eg, in a Caltech colloquium. The presenter's theatrics was a dead giveaway for snake-oil salesmanship.
terrible talk
So much BS. I cant even imagine how they are allowed to speak at TED.
How exactly do you consider this as bs...? Her entire presentation is already rooted deeply in the fundamentals of quantum mechanics. A lot of what she said actually already exists in some ways already in present day.
Nothing she said hasn’t been proven, or not demonstrated in at least an elementary way. It all already exists, its about being able to refine and scale quantum technology for use on a wider scale that we are still figuring out.
