Finally, someone was able to break down quantum computing into something more easily understood such as quantum physics.

Actually, it was not Feynmann but his colleague, junior and friend Edward Fredkin. It was Fredkin who explain the language of the computer to Feymann and in return, Feymann helped him understand Physics. Fredkin wrote the very first reversible algorithm, and it was his idea to build a quantum computer. He even went further and wrote about the simulation theory of the universe.

For anyone interested in learning more about quantum computer programs (ideally familiar with Linear Algebra first), IBM has a number of guides to quantum computing, a program simulator, and online access to a real quantum computer--all free. You can literally run programs on a quantum computer in New York from your home. Or Antarctica (yes, someone actually does this from Antarctica). Thought I'd spread the word a bit. Have fun!

I don't exactly know how I got into the "Quantum" rabbit hole, but it's a really fascinating one! I'll admit, I don't understand all of what is covered; I'm probably going to have to watch this multiple times for it to make sense. But this is really fascinating and exciting to see unfold. This must be how those of my grandparent's generation felt when desktop computers were becoming more commonplace!

This channel is so underrated. It's one of the few channels I have the bell on.

1:44 That is simply the most beautiful handwriting I've ever seen. (And/or an average font)

Quantum physicist walks into a bar. Bartender says, "Weren't you here tomorrow?" Quantum physicist says, "No, but I'll be back yesterday."

Kudos to the motion graphics editor in this video. They really aided comprehension here.

The content is very professional

I think this high quality content with zero hype will be very motivating for people that want to study this topic properly. Thanks! 👏

Thank you! This is the first explanation of quantum computing I've seen that goes to this level of depth but is still understandable by the layman who knows a little bit about quantum physics. Most sources just say "superposition, voila."

The content on this channel is always good and simplified.

That quantum computation animation thing was really great. I wish you could made more about it

I have heard some of this before, but the standard explanation with "qubits store all the values from 0-1" or "do all the computations at once is the simplistic explanation that is repeated so often that the only thing I can really remember is "that is not how it actually works". I hope this video and the article on the website is something that will help me remind of more details.

This is the best explanation of quantum computers I've seen so far. And I've seen a lot of them.

Keep up the great work scientists! I don't know much about physics, but I'm proud that there are good people keeping us moving forward.

Great video...Props to the animation team for making such good visual effects :)

amazing. It should be twice as long! I crave more high quality quanta videos!!

been watching documentries on quantum theories since i was eight but have to watch this a few more times to fully take it in

"it is not unreasonable to imagine that information sits at the core of physics, just as it sits at the core of a computer" -John Archibald Wheeler (1911-2008)

This is the BEST explanation I've seen in almost 2 decades of just HOW a quantum computer actually works. I've understood the concept, but for the laymen this is the most useful breakdown I've seen, and in just under 10 minutes, well done sirs.

Humanity is always at its best when it walks towards darkness. Glad to see people out there doing what is truly hard.

Best video I've seen so far explaining what quantum computing is. Most try to simplify using confusing analogies.

Finally , the best video that explains the concepts, I' ve spent months looking thru Quantum vendors, for a good video. This is by far the best!.Quantum Computing Companies, should have this video as general intro.!!! great job

I would argue this is the single best short introductory video on quantum computers. Absolutely phenomenal work by Quanta here. Preskill and Aaronson are top minds in the field by any measure. The information is accurate and beautifully presented. 10/10!

Great video and amazing explanation from outstanding researchers, thank you quanta magazine !

well explained and mad fascinating! subbed!💯✨🙌🏻

I like the ending statement about when we “have a quantum computer to play with”, makes me look forward to what our world will come up with next 🥳

These videos are so good!

Really interesting, got me curious of how exactly are those amplitudes manipulated. I think it would be great if there is another video with a simple example.

This is such a great explanation of such a complex topic!!

This answered all my questions on quantum computing - thank you!!

Awe-inspiring video! Thank you greatly, I loved it!

What an amazing country we live in where scientists who are working on this and my neighbor who can't read or write have the same rights and law's. This is truly a just and an amazing country. Idk why it popped into my head but it did.

I didn't understand a word of this video but i can say its the best video i have seen on KZfaq so far .

finally understood how the qubit works, great video

9:13 when a physicist says im not sure if there's any money to be made that's when you know there's money to be made

Extraordinary video and explanation. We are going further and further into the future with this. A Quantum time machine.

Bravo!! That's the best presentation I've seen on this particular issue. You've just gained another new subscriber! Warmest Regards to all who are watching this, instead of the football, lol!

Wow, this is awesome! Can I ask, what software is used to make these animations?

This video is so well done, approved (I'm a quantum optics physics major)

would love a breakdown in the engineering/design aspect of the chandelier. How the loops and tiers play a role and achieve close to absolute zero.

Awesome video. Some of the best and most accurate brief explanations of quantum computing out there.

Thanks for the visual aspects, they definitely help.

Finally understood!! 💛 A relief. Thank you guys

I was watching another video on quantum computing that said every time you added another Qubit it double the the overall processing power of the computer. If I'm remembering that correctly and that is true that's *amazing!*

Beautiful! I enjoy this type of content when I'm stoned.

Clean and precise information. Thanks quanta Magazine

Thanks for the Good presentation. Scott was to the point. Great

The call to the IT department when its not working: -"have you tried turning it off and turning it on similtaneously at the same time?"

What is often not explained (including in this video) is how extremely difficult (or impossible) it will be to program these quantum computers and the entanglement interference from the ambient environment. Information = energy. The laws of thermodynamics will hold and ensure that a tremendous amount of energy has to be input to harness the computing power.

You can create a superposition by simply running the rand function and calculations client side but from the server side it is viewed as the data storage being in a superposition of all the clients states

probably the best laymans explanation on youtube and I STILL can't understand quantum computers!! i wonder if I ever will

I love these videos. I’m so excited to see where this technology ends up taking us.

Love this! So well presented!

finally ive been looking for an answer of how it works further than just saying entanglement and superposition and this did it

This is basically saying that nothing is random, if you have a construct of every possible outcome, quantum mechanics is beautiful

Nice video, quantum computers are so weird to me I find the need to watch many different explanations to reach an elementary comprehension of the concept

Your videos are awesome ❤

Thank you for the briefing

Excellent introduction, thank you.

I didn't really understand that 😂😂 fascinating nonetheless. Also, please, more content like this.

Amazing. I can’t wait to see what humanity can learn from further exploration into the quantum realm.

Interesting explanation, made simple but rigorous

Nice. An explanation of a simple example quantum circuit or algorithm would be more interesting and helpful.

Amazing work Quanta, we need more content like this.

Great content! But this video leaves me with more questions though. Eg, how would one describe the concept of Amplitudes mathematically? Why would you need 16000 bits to describe the outcome of 1024 qubits?

I'm thinking about what improvements can a quantum structure give to machine learning applications over that just computational power upgrade... Any guess?

Down to a nutshell for people who don't understand quantum math just imaging your current understanding of binary bits as if viewing something only in 2D like for example a comic or a book, now imaging you're given a holographic 3D television. That's the leap between the two, it's the next level the next spike of technology growth.

I don’t know why I’m here. I don’t even understand how regular computers work.

Quantum computers are the new Fusion reactors. See you in 70 years guys.

That was incredible. I watched all nine minutes and fifty eight seconds and still have absolutely no idea of how quantum computers work.

So we gonna figure out what to do with the machine after we build it! Wow👍🏽

In my work we build simulation models. A very important part of building models is the use of assumptions - information that is not necessarily true or accurate but allows the model to work well enough to produce useful results. Quantum mechanics has indeed produced useful results over its 100 year history but there is a catch. We have forgotten that the assumptions of the quantum model are not actually laws of nature: they are ASSUMPTIONS. surprise surprise. Quantum physics is a mathematical model created to understand the behaviour of the election as observed in the hydrogen atom. These assumptions while they "work" defy common sense and the greater body of physical observation. Let us not confuse that they are assumption and not reality. There are classical explanations for the so called proof experiments by modelling the election in a way that appreciates it with form and substance. The unveiling of this true understanding will be the dawn of a wonderfull revolution in science. Let us stop chasing mirage assumptions in the hope that they are real

The more videos I watch about quantum computing, the less I understand quantum computing

I can’t say I understand it, but it does give me a deeper appreciation.

I have a question, how is the value of 2^10 been calculated at 6:23 ? I thought a qubit can store 0,1, and the answer between 0 and 1. Does that mean I can treat the value between 0 and 1 as the third possibility? (for instance, 2) why wouldn't it be 3^10? Also, 128 bytes is equal to 1024 values, why does it say 2^10 is equal to 2 kilobytes? I think I am miss-understanding something, hope some people can guide me Thank you.

I was just telling some friends how I understood quantum computers to work, and then I watched this video to make sure that the information I'd given them was actually correct. The wave function for my explanation appears to have collapsed in my favor.

I've always struggled understand the output of quantum computing and this video has maybe made the answer more accessible. While the Q computer is general purpose in that it can be programmed, the output is more like an analog computer rather than digital?

Great description

Finally, but watch Arvin Ash also. The order depends on what you know about QM but together, you'll be much much closer to conceptualizing what it's doing, and a little closer in his it could work. I think that's the key.

Two questions from a total novice 1) Does this open the door to -1 possibilities in previously binary computer programming? 2) Does the relationship between particles and/or waves become more of a predictable enmeshment rather than simple entanglement when that relationship has been definitively observed?

Holy cow, I loved this video

I hope it will be a breakthrough for the man kind in calculating the future possibilities.. Or in simple language as shown in many movies.. 'It will help us to see the future', by the help of this super fast compution capability..

This is truly fascinating.

I would like to become a Quantum Physicist, this science is truly incredible.

A Russian mathematician Yuri Manin was one of the first to propose the idea of a quantum computer in 1980 with his book “Computable and Uncomputable”.

This is absolutely amazing. And such complex concepts to normal people like us becomes a little bit easier when we have access to information so beatiful desinged and expressed like in this video. And everytime gets harder to understand how deep is this and how it can drive us to knowing the behaviour of all the pieces of our universe. Thank you so much. Good information is only spread by blessed people.

Thanks a lot for the info!

I've had this weird pet theory about creating a "block" of not numbers, but rather computational algorithms. Arranging them from simplistic to complex in a series. The idea being, you send a series of formula through with a substitution of all potential functions being mad-lib'd with this block of algorithms. The result of which, I feel would potentially map out the potential patterns hidden in numbers and by relation the potential avenues of travel quantum computations are utilizing to reach a proof.

Plot twist: this computer does not support gta 5 💀

Well explained with animations

Sir plz make a video on non linear optical materials.

if we can somehow use quantum entanglement to transport information from a place to another instantly it would be crazy like we can use it between stars or even galaxies

Great content! Keep it up team. However, most of it went directly on top of my head. I'm not qualified enough to understand this. I'm trying to understand quantum mechanics, I hope someday I will be able to. :D

Would it be possible to record the exact details of a given area using Qubits? Such as to take an extremely advanced picture, Or to collect remnants of audio?

I felt a bit misled after ( 0:30 ) because i got really curious about the potential applications and then at the end it's basically there are none (yet). I really enjoyed the vid though, very well made for my peanut brain lol

Computers back in the days used to be huge and occupy a whole room just to process or store just a few KB's of data. This reminds me of that stage when humans had just invented computer, I'm pretty sure one day we will be having tablet, mobile or laptop sized quantum computers all around the world. The world would be a whole different place with that crazy amount of computational power.

nothing is explained about quantum computing in this video
