No he said we will soon achieved Quantum Supremacy. We will do something on a quantum computer that we cant calculate at the same speed on any other (super) computer. What we calculate and how we use that has yet to be determent. He also says that with Quantum-computing we will be able to raise the ability to calculate by magnitudes (7:20). It is kind of like Nuclear Fusion, we know we need it and that it will bare rich fruits in the future but its future and when it will be, we don't know yet.

I've watched many video that sorta explained quantum computers and they mention superposition and entanglement but I couldn't make sense of how they come together to have this powerful computation effect. You actually made it make sense to me. I'm subscribing.

Really liking the addition of this format, Professor!

Thank you, just came from your TED talk, you've got a new subscriber. :)

I like the pace of video. Informative, didn't got bored, cute quantum computer illustration 😛 Keep it up. 👌

I know a thing or two about quantum computing from an introductory paper I wrote for school about the mathematics behind it, and I have to say that I'm glad you didn't delve into the 'checking every answer' explanation. That may be a valid way of thinking about what happens before you observe the qubits, but it gives people a false impression of the power of quantum computers. Amplitude/probability amplification is a far more accurate way to understand the benefits of Grover Search. Great video!

I found this channel today and I just want to say that I like your videos a please keep uploading them

Good honest assessment of the current quantum computing environment.

Excellent video!!

Really enjoyed the talk, but I would have really liked to hear what kind of problems will quantum computers tackle and in what kind of computation are they better than classical computers with real life applicaitons in mind. Geordie Rose at D-Wave (back in the days when he was working for the company) always brought up the traveling sales man problem at his presentations and the "finding of the lowest energy level in a valley". I think these examples are cruical to mention when somebody is talking about quantum computing and what it is actually "good for". In the case of the gate model quantum cryptography is something worth mentioning.

Thank you for the video ! As for the sampling problem: do you think a quantum computer could be used to generate random numbers with a better quality than classical ones? I expect successive measurements to yield uncorrelated samples. Could a large number of measurements be done in parallel or at very high-speed, to generate good-quality random numbers in real-time / compete with what maybe a GPU can do? Measuring in parallel several parts of the systems (i.e subsets of qubits), if possible at all, would I guess yield correlated samples...

Your videos are very helpful for me since I’m really interesting in Quantum Physic.There’re a lot of things I’m curious about that are explained here. So thank you and there’s no way I’m gonna stop subscribing.

Saw your Ted x talk and am super smitten by you.

Hi and thanks for the video. Can you explain me more about how it is possible to control the degree of superposition and also how more than 2 systems at the time could be intricated ? I can understand several qbits form a system having its own state but it does not mean each individual particle in it is intricated. I like the fact that both models are presented in your video, the annealing and the gate models, but here again I would have liked to know more about it 😀.

I searched "quantum physics" and watched a TedX where you spoke about quantum physics for 7 year olds. While I was listening I had opened a separate page and scrolled down on a search of "quantum supremacy" and for some reason clicked this vid and it's you. I scrolled past a dozen or so vids and randomly picked this one with no idea this was your channel.

Great video, thank you

Could you make a quantum computers video at a difficulty that you would show a quantum computer scientist? It would be really cool to see just how elevated the dialogue gets in that situation and just how much someone watching on KZread could understand.

nice explanation, thanks

Thamk you for the information sir

Very usefully information

There's one thing I don't understand about quantum computers. They work off of probabilities. It's all based off of probabilities of certain states when you measure a superposition. You build up distributions. If that's true then how do you get a definitive answer. Like what if you're just really unlucky. Is it possible to get a wrong answer, because it's just probabilities?

You can't get a definite answer. It's a paradox. Probability ensures that possibility remains.

*Incorrect* . There are huge prospects for quantum computing: There are a lot of materials online showing in how many algorithms quantum computers would have an unquestionable edge. Just think, non determinant or random algorithms are just about everywhere, searching, machine learning, decrypting, and just about any np-completeness discussion can involve quantum computing. And think about a random process being entangled with more information.

Awesome explanations, yet I still don't understand how does classical computers compute. What happens inside a CPU and its transistors that it give us 4 for 2+2 . Would you please make one video for that ?

Hello there. Ion trap quantum computers are classified as universal quantum computers. You can implement the set of universal gates {C-Phase, C-Not, T, H} on the ion trap system and make up circuits that are equivalent to circuits set up on a superconducting system.

The way I see it is that quantum computers can help you when you’re not sure exactly what you’re looking for and you want a clear path. But they're not fundamentally better than classical computers if you already know what you’re looking for.

You should do a video on enviormental science

I thought a quantum superposition was the state of some qubit or something existing in one or more places/positions of some domain or such at once? (e.g. such that someone could exist in multiple places via cloning or such) And that quantum entanglement was of how some qubit or something being mutually connected without any direct physical relation or connection, such that they can be related/connected without direct means and be affected as such (e.g. similar to how Leigh, Luke and Ben Solo all eventually affect each other via some means of the force -- or rather, a quantum entanglement if applied in the galaxy far far away)

Some map video would be Nice haha

Do a map of Astrology, the Science of all Sciences

What animation/video software do you use?

Wasn't Entanglement when two superpositions were linked such that they would both give the same result if measured in the same way? Simply having multiple Qubits in superpositions is enough to grow your effective simultaneous states 2 to the power of the number of Qubits. Or do Qubits need to be entangled to work properly in a calculation? (And measuring each Qubit in a different way gives the data of seperate bits?)

This is Gold

So quantum computers can mainly be used for simulating?

So you need a high power classical computer to work out the result of the zillions of quantum quasi-random number runs? But probably less calcs then a classical computer running all the permutations?

Would it make sense to have quantum computer sections of classical computers like a new processing unit on the mother board?

@OleTange

Most likely no. There are 2 reasons: * The problems that QC can solve are typically problems that are only interesting to researchers. A QC will not make your game run faster. This means there is no consumer market for QC. * Qubits have to be cooled to less than 0.0001 K (= very cold). I do not see anything that is going to change that any time soon. So while I do not think we will see a QC in every home, I think we will see a QC in every datacenter. By having one in each datacenter it is also likely that you as a consumer can use this QC the few times you may have a problem that is run better on a QC. In other words: QC will not be on your motherboard, but will be available through your internet connection when you need it.

In the very long term, maybe. Quantum computers are only as good as classical ones for most tasks, and classical computers will (probably) always be easier and cheaper to manufacture, however there are some tasks that quantum computers will offer serious speed up, but really only time will tell whether there will be enough genuinely useful applications for a quantum computer to justify putting them in a regular machine. to address the other answer, there's no reason the believe that the future problems solvable by quantum computers are only interesting to researchers, and there's no reason to believe that (far in the future) quantum computers may not require such extreme environments - low temperature and environmental isolation - or that the facilities to create these environments will be small enough to be on-chip. I do however agree that, when quantum computers first start to be a thing, this will certainly not be the case and they will likely be confined to specialist facilities only accessible to rent via the cloud.

So will quantum computers Use transistors because it would be hard for the superposition to be possible on a transistor

so a quantum computer capable of processing the superpositions on qbits long enough to simulate all probabilities possible in universe could be a key to find optimum state of energy when applied to some kind of task?

I've watched a number of QC videos by now, and I can't wrap my head around how they could ever work. If every Qbit switch in a given logic gate has only a statistical chance of permitting or stopping a current, how could a QC's operation yield anything except noise? Such a device would cease to execute its commands the instant you turned it on. What am I missing?

Maybe Im naive as I work in IT and my interest mainly lay in network engineering. Love the example of qubits, thankyou. It makes so much more sense than other videos trying to exllain this. Secondly, Id like to ask - with the knowledge you have now and Google (the worlds main search engine) keen interest in google home technology and large investment in quantam computing, do you see google becoming somewhat of an end prediction of George Orwell's 1984. Is it possible for these computers to think as an entity or do we program them the same as we program "classical" computers? Also if a quantum computer can always win with a series of qubits that can represent nearly every outcome, what exactly are we going to use this for in everyday life? Do you believe the only true use is to create control in society? Ps. By the "worlds main search engine" I mean, they are meant to be a search engine! Not trying to creep into people's lives with technology that can control and listen to the inner workings of our lives.

Yes. If you build it. Right now, the physics community say no but you know nothing is impossible.

Instead of 'electrical' switches that are either 'on' or 'off' or a rheostat with analogue settings, why not utilize the photon as the 'switch' of which the cycle itself of the photon could be adjusted. So basically, a single piece of information could be any point along the photon's curve, or even within the photon itself. Could pack a lot of information into a single photon. And then consider how many different energy frequencies of photons there are. That's a lot of information.

I don't get what's the point of having a superposition state, if you don't know if will get 0 or 1 (you know only the probability). What I mean is, in classical computing you can use 0 or 1, giving them meaning, because you know the value of the bit. Can someone explain please?
