31:45 Summary - Наука та технологія
A short 'war story': I spent 17 years in supercomputer field (Cray Research, Thinking Machines, etc.). In 1992 I completed a project to mathematically construct the first N elements in the periodic table from first principles (using Feynman-Kac integrals while accounting for spin). I used the 65,000 CPU Connection Machine (27 Gflops, $18 million). I was able to compute the ground energy state atomic structure up through boron (N = 5), within 16 hours. Today, researchers may be able to reach N = 30. It is clear the only way we will be able to simulate molecular biology is with quantum computers!
Great story thanks for sharing! What did you write it all in if I may ask? Fascinating history. Would you tell us more of some of the challenges you faced?
I am so excited to see what quantum computing will do for the fields of molecular chemistry and protein engineering
We're already making breakthroughs with classical computers and have incredible potential with neural networks....but if we could use a quantum computer to model the system? Just program the energy function and get out the lowest energy state solutions? That would be the silver bullet. The golden ticket to understanding all of biology, even the entirety of cells at the atomic level.
You may be too optimistic.
@@waclawkoscielniak9291 that is what people said when computer scientists back in the 30s and 40s claimed computers would be smaller than the size of rooms
@@ithaca2076 facts quantum computers are in the stage classics computers were in the early 30s . Yes it’s huge and the application is only for research applications . But now we have a 1000 q bit machine now. And I think Moores law will apply to QCs . We just need time .
I shed a few tears of relief ... this presentation has given me yet another sliding door moment. I love the illustration, pace and most notably; the objective approach. Not many content creators deliver with such transparency. Even fewer speak from a place of exposure. This is one of the few moments the algorithm has come through
Hey thanks! Yes I very much care about these things so its really nice to hear them being noticed :)
Hello everybody, thanks so much for all your really nice comments! A lot of you have said that this is the best introductory quantum computing video you have seen, which really puts a smile on my face. That's what I was aiming for so I put loads of work into it and I'm glad it paid off. Thanks for taking the time to write a comment, it means the world to me! All the best, Dom
💜
Thanks for putting the effort in creating these maps, it really puts all the information together in one memorable image. I would stick these all on my wall for inspiration, though I can't afford to buy them all. I went on Flickr through your provided link, but I cannot seem to be able to download any of the images. Is is supposed to be downloadable? Thanks for all your work!

Error correction and instability was a huge barrier in early classical computing too. Geniuses like Richard Hamming spent their entire careers developing error correction schemes to get these reliability problems under control.

"You don't need to subscribe or anything..." - Subscribed my friend, one of the best videos of quantum computing on YT.
Just finished taking a course in Quantum Computing at my university, and it was so cool to hear you explain all these topics and be able to follow along, while also hearing about some of the things we didn't cover in the course!
I am planning to take Quantum Computing myself. Wanted to know.....
1. How is it?
2. Is it worth taking?
3. Can you take it as an Undergraduate?
4. If not, How do I take I go about, if I want to take Quantum computing as a career.
This guy really makes it easier for me, since i learn faster when i have a high view over the subject. Nice work and i hope to see more!
Yeah, I feel more confortable learning with a high view too
even nicer when you're already high watching it and getting a high overview as well
log n nice
Yes, he's so good that I almost understood.
@@justgivemeanumber8215 This is what I am doing right now, I'm stoned and I'm watching it.
This is an incredibly informative and all encompassing work on introduction to quantum computing. I just wanna say, the UA-cam algorithm should suggest this video to each and every one of the users who have ever searched for phrases like 'quantum computer' or 'quantum computing'.
This is by far literally the best video on quantum computing. You have explained this complex topic in such a simple manner, it not only helped me understand what they are but also enabled me to think about how I can use them to solve problems in my field. Thank you so much for your hard work.
*This isn't simple. It's dumb as hell.*
I see, so how exactly does a quantum computer work in your own words.
wow, as someone who's always wanted to know how this worked (i've watched other things about QC), you really have a gift for teaching.
In 28:05, the Flux Qubit are also called Fluxonium in the industry of quantum chips. The current leading company is Alibaba from China with a the single-qubit calculation accuracy of 99.97%.
The pedagogical quality of this video is absolutely astonishing. It's superb in terms of clarity, plenty of examples of applications for reference, good analogies and incredibly accessible as an introduction.
Small blunder at 9:08: "Is it twice as hard or even exponentially harder?" If you add a digit and the problem gets twice as hard (repeatedly), you have an exponential problem.
Yes! Haha I spotted this just after I published it and I did a little facepalm. Yup doubling is exponential! Durbrains.
Outstanding nerdiness! 😁👍

A quick note to say congratulations on such a lovely video. I'm part of the product team at Quantum Brilliance, building room-temp quantum computers via diamond NV technology, and I'm always looking for great examples to share with people coming into the industry. I really appreciate the nuance you unpack here too, and I think that's something that's going to be particularly useful, especially for those coming from FAANG roles who are curious how to get comfortable with the fundamentals even as they join and focus on their areas of business. Great work mate.
I just found this pure gold. This is probably the best video of 2021. Your skill for clear and direct explanation and also systematic approach to the topic is inspirational for me. Also great graphics!
Man! This is by FAR the best explanation of quantum computers I've been able to find so far. Thank you very much for the astonishing amount of work and research there's behind it. Really good work!
I swear to God, your shoutout to Qiskit was the only add on UA-cam ever that I enjoyed watching. Also amazing topic and thank you for helping me to write my Quantum CS homework. I really love this channel.
this is the greatest video i have ever seen. I can not express my appreciation more. Even the sponsorship part - never been so engaged in an ad. thank you!
You are so unbelievably clear, its astounding. You've turned a week-long paper-reading rollercoaster into a 2-day endeavour. Thank you very much.
You had my curiosity, but now you’ve got my attention!
It’s been a while since I’ve been this stoked about learning and progress, thank you for such clear and articulate explanations. I love that you’ve thrown in terms outside the scope for those want to dig deeper.
I’m about to study the shit out of this!
😂
Intr
This is hands down best beginner's guide to quantum computing. Most of the other videos I watched were very brief and not really going into the actual working. This gave me a very good intro knowledge about quantum computing. Thanks for the video, well done!
Real science and real scientists are such a joy. They make the world a better place (at many levels) by looking for truth and being truthful about looking for it. Thank you for this video!!
Good on you to help us by giving us the basics of the topic with clear steps and vivid illustrations. I have not found any other video as clearly explained with graphics and animations as this one, after watching about 5 or more. We need more videos like this to explain complex matters.
I understand how much effort it takes to learn all that and convert it to an infographic. I really appreciate this effort. And the outcome is awesome. Thank you!
Thank you for making such an excellent video with clear illustrations to explanation of this complicated topic. I'm blown away that you covered so many of the details in only 30 minutes!
This is without a doubt the best explanatory video about Quantic Computing I've had access to so far.
Excellent material, thank you so much for sharing this amazingly structured knowledge.
this is brilliant
simply brilliant
i have never seen any description of quantum computing so clear and well described
thank you
Very well made video! Finally clears the important points of this complicated subject
That's by far the best video about quatum computing I've ever seen! Although I have a good physics background and have seen videos/lectures on the stuff, I hadn't grasped how exactly qubits can be actually used to improve computation and how they represent a new paradigm...until now! So, thanks for the spetacular video and for such high quality popularization on the topic :)
This is an incredibly well put together video, between the hierarchical approach to the topics and the easy to understand visuals. I've read about quantum computing a couple times prior to watching this video, but the sphere visualization made things so much clearer for me, coupled with your amazing educational skills.
Thank you. I know just how much effort goes into making this kind of content and I'm greatly appreciative of what you do.
Thanks for this very progressive, clear and accessible and yet pretty thorough mapping of that space. Looking forward to watching the next one.
Just recently read a book about chaos theory and it talked about weather forecasting - specifically, how difficult it is to accurately predict the weather beyond a few days. This boils down to how complex systems such as weather are self referential and as such even the smallest changes in one of its parameters will eventually lead to a massive change down the line. We are talking about how even a millionth decimal place in the speed of wind could eventually lead to massive changes down the line and this change is not linear in fashion. I think that's where quantum computers could be quite useful as we can model the entire ranges of a parameter using qubits rather than trying millions of combinations for a slight change in just one parameter.
Your simple overview of this subject and the use of graphic drawings is astonishing!
Thank you for an astounding and fantastic video covering the quantum map. This is massively insightful!
One of the best videos about quantum computing I've seen yet. I'm getting my MS studying quantum computing, focusing on the software side, and there are few good resources on or offline explaining quantum computing and it's advantages and disadvantages to a general audience.
Do you know any good resources to learn how to start thinking on how to design quantum algorithms?
The language of quantum is linear algebra so I’d start there if you don’t already know a bit of it. You can then go on to learn about quantum states, and operators on those states like the Pauli matrices and different operators composed of the Pauli matrices like the Hadamard gate. Then I’d say start with Deutsch’s Algorithm and Grovers algorithm. Quskit and IBM actually have awesome resources for learning all this, and IBM’s circuit composer is super cool to play around with too. If you aren’t too interested in the physics of it all the textbook Quantum Computing for computer scientists is pretty good, although it skips over a lot of the physics that, until better error corrected computers are available, is really valuable to know.
@@georgegrattan7319thanks. I guess I'll look up Grovers algorithm and continue watching the rest of the Qiskit youtube series.
I have watched some of it before, but I sort of burned out from the feeling of knowing how to follow the quantum circuits and calculate how the state changes, but being frustrated at having no idea how to design an algorithm for it to calculating something.
How does the software side of the field look? Is it going to be monopolised or are there a fair few competing developing softwares?
@@stretch8390 Right now, at least to my knowledge. The software side is largely sill theoretical, since we don't have an error corrected, many qubit computers to run the software on. Looking around for internships or jobs on the software side largely put you in a large tech firm like Google, Microsoft, or IBM but there are tons of startups that I believe that once the hardware tech is better, will need quantum software skills.
What an amazing video. A lot of the explanations of quantum computing I have seen are afraid of going into the weeds, because it becomes less accessible. You have balanced introducing details without overwhelming the novice expertly. Thanks a lot for your work!
Excellent overview. I've been struggling to find just such an overview. I needed to see the forest before I huge one of the trees.
I really appreciate the way you present this material. It is fascinating.
3 minutes and everything is clearer already ! this is perfect, thank you.
This is a GREAT video to watch. I learned so much, I'm going to have to watch it multiple times. Thanks for posting this, it really helps!
Thanks. These maps of videos just hit the right level of depth and explanation for me. I am especially looking forward to simulating living molecular system like organelles and even whole cells on a quantum level to understand the complexities.
Dominic, I absolutely love your videos, and just wanted to give big props. In particular I appreciate the transparency of this one, with Qiskit being the sponsor. As a matter of fact I just went to their website because of the transparency -- makes me trust it more. I loved "elementary particles" as well, and got myself a xmas gift of the poster, because supporting such high-quality is, well, important. Keep it up!
hohoho my iq is increased
This quantum shit is better than Elon Musk
I deeply appreciate your efforts in creating this outstanding educational video. Watching this 30-minute presentation on Quantum Computing was truly enlightening, and your delivery exudes professionalism. Well done!
i think qiskit can improve their documentation a lot if they just ask you, as you have a brilliant way of presenting things. Thanks for making this video
@9:44 the map states that "Shor's algorithm is polynomial log(N)". This means it's polynomial with respect to log(N) right?
Edit: I just googled it. Shor's algorithm runs in polylog time (polynomial time with respect to log(N)).
Yes, but the "N" on the wiki is the number itself. The number he used is the number of digits of the number.
log n nice
By far the best explanation I have ever seen. I learned a great number of aspects that have evaded my understanding for years.
Well. This is the FIRST time anyone has been able to explain this to me. Thanks you so much.
Spectacular overview. I just finished the MIT XPRO Quantum Fundamentals course. You summed it up here in :30 minutes! Brilliant.
If youre proud of that and you are using this video to help guide you there is a high likelihood you havent learned a single thing.
@@ThunderAppeal negative much?
Amazing video 🥂, because of interference we can't achieve 100% in the field of Quantum computing but combining classical computing will help. In university of Qutech, scientists successfully created an quantum network using hybrid approach. It will be really helpful if you mention this in your upcoming video 😊
Very insightful and awesome, it is amazing the way you combine simplicity with technicality and still not lose sight of the overall aim.. which is to enhance understanding. Thank you!
This is as simple explanation as one can get. Love it. Thank you 😊
This is AMAZING!!! Your so talented at teaching science. Keep up the great work!
Really cool to see topological QC mentioned here! I'm working at UCSB to start studying topolgical superconductors and hopefully prove experimentally the creation and manipulation of majorana fermions!
Good luck! This was definitely the most exciting part of the video for me, and I hope this technology pans out.
Same! My PI, Dr. Island, just came from UCSB and one of my labmates is working on realizing majorana fermions in 2D materials.
Hey, this video is super useful to me. I started learning Quantum out of interest, and at first was intimidated by the physics formulas. This video helped break down the macro themes for me to understand. Right now, I'm using Qiskit as advertised in your video, and its really a great tool.
Everytime I find a youtube channel that simplifies such difficult topics its gold, thanks a lot!
I'd imagine weather boils down to simulation. It would be better at predicting position and movement of atmospheric conditions.
It also would be great with running diagnostics
Thank you for another excellent video, makes me feel excited about the future!
if only every subject study showed to students like this, the worlds education would improve to a whole new level, because i never even touched QC and how it worked, i just heard it is a better computer, but in 20 minutes, i really got the gist of it, thank you
This video is way better than any of the Quantum Computing Introductory videos I have ever watched.
I think your next video on the current research efforts and their progress so far will be very interesting. A good benchmark would be the size of the integer they can factor. Wikipedia lists results but some of them look quite suspect. From the results listed, it seems that you cannot just put in a number and get out its factors. (I imagine that not everyone is working on factorization, but a lot seem to be.)
Probably doing more to advance the field of quantum computing by presenting it in an easily digestible fashion for the next generation to be inspired than alot of efforts actively working on it (not to discount them). This is great
It is the first time I didn't fast forward the in placement ad. Thanks for Qiskit supporting the video
This is brilliantly done, I finally understand the concept and I love the examples!
You have a knack for explaining complicated things clearly. This was helpful for me. I’m an EE and programmer and have the goal of learning how to program quantum computers. I’ve been using qisqit to learn about quantum gates, but it is taking forever because I’m really trying to understand each step I take thoroughly - because I know what’s coming, a point at which I will say “the universe cannot possibly work like that”. In fact, my goal is to prove to myself that it DOES work that way, by accomplishing something with a quantum computer that clearly demonstrates its quantum weirdness.
You mentioned that a classical computer can be made from just nor gates and bits, but of course bits can be made from nor gates.
Superb job! I did my theoretical Physics PhD fifty years ago but this was absolutely refreshing! Keep up the good work!
He presented on this topic at my school,a nd up to this day, that still has the most impact and impression on me with regards to the motivations and actualities behind quantum computing.
How is it possible for one person to know so much! Dominic you are unreal (in an amazing way).
Love the authentic hardwork you put in each pixel on this video, these videos' butterfly effect will inspire millions of future engineers to change the lives of trillions of future civilzations.
I'd love to see your take on robotics roadmap, for people who aspire to work on robots like the ones from Boston dynamics or even rovers on mars. Cheers mate!
Plz help those students who can't go to school in this corona pendamic one click for them plz support
*You're wrong.*
May we get a Map of Artificial Intelligence in the future? I would instantly buy that poster/ canvas print and put it over my desk for motivation!
Thank you!
I want to congratulate myself for persevering to understand quantum computing by reading and listening to countless number of articles and videos that made no sense with the belief that someone like this gentleman would have a clear explanation! Thank you!
Cant thank you enough for all that you have done for such a spectacular presentation and I'm writing this pausing at the half of the video.
I'm a student at UNSW studying EE/Math and I think i'll definitely take some quantum electives in 2022/23 considering how amazing this all seems! thanks for the great video.
Very well explained Dominic, thank you. This helped a lot in furthering my understanding in quantum computing. I see you quickly touched on it but AI seems like a great application for QC's. In a recent video Veritasium touched on how analog computers are somewhat more effective and efficient at computing neural algorithms (simulations) than classical computers but it seems to me that quantum computers would be even better. Don't ask me how exactly because I just don't know but crunching vast amounts of data seems to be a QC's bread and butter. This is all big brain stuff for someone who is used to binary!
I love Science. And you?
The best summary that I've seen so far. Congrats!!
Finally! Veritasium, Arvin Ash, degrasse-tyson, smarter every day, physics girl... and the list goes on. They've never been able to explain superposition in an understandable manner. You've done it. Thank you
Really well made vid, I’m currently getting my MS physics (focused in Quantum Computing) and can’t believe how well you explained this. I really appreciated the idea at the beginning especially in referencing the “power” in Quantum computing comes from the amount of states (~2^N) the computer has access to without getting too deep into the linear algebra. It gave me a new perspective on how to look at things as well and I plan to finally buy one of your posters! Keep it up, content like this is really appreciated!
Best of luck for your ms mate
@@binamra5521 Thanks, I'll be graduating at the end of the month provided that the stress from finals & projects doesn't do me in too much XD
I am new to your channel, you have a gift of explaining complex topics in a way that it's understandable to a layman like me.
You and Sabine Hossenfelder are my favourite scientists educational channels, in my opinion, the best at what you do.
it's not a gift, it's a trainable skill you can learn too. He have trained to be good at teaching.
@@immko I think it's a mixture of both. I am pretty good at explaining things that I understand, naturally. I have had zero training in it.
But these are some of the most complex subjects that humanity has ever tackled, to be able to explain these subjects is on a completely different level.
@@noisemagician I don't know you so I'm just guessing, but if you've enjoyed teaching for a longer time then you probably have been trying to get better at it for most of your life, at least after you discovered liking it.
Topics DoS teach are complicated things to learn, but not necessarily so hard to describe after you familiarize with them enough, also considering he seems to enjoy teaching so he probably have done it for a long time and if he wanted to honestly improve in that then he have done it quite effectively for several years. You get really good at anything if you train effectively for several years.
Also because we can't be completely sure if there is such thing as "natural talent" or "gift" I think it's more beneficial to believe you can learn everything you put your mind into instead of handicapping yourself by believing you might not have gift for something.
@@immko I enjoy doing it it's not my job or anything but I am good at certain things and I enjoy teaching other people what I have learned and enjoy doing. I makes me happy to see them ''get it''. I might have gotten better at it over the years by practicing.
I somewhat agree with you, I think that a lot of things can be thought and learned, with practice even perfected. But there is a limit to that, a simple example would be Francis Nganou, the current UFC heavy weight champion. He has been training for ONLY 5 years, he has what they call ''the touch of death''. If he connects he will knock you out.
Power punching is one of those things you can''t teach. Any person can learn to punch harder but no matter how hard and how long you train you will never be able to generate as much power as him.
I think the same applies to mental feats as well. You can get better at mathematics and physics but no matter how much you practice you will never be as creative and smart as Einstein or Newton.
We can always improve but we are limited by our genes and the environment that molded the expression of those genes.
@@noisemagician That's where our opinions seems to differ. On Francis I agree completely, it comes from genes and if you don't have them there is nothing we can do, at least before crispr gets better or something similar.
I do disagree on the mental side of it, I really believe nobody is born with 200 IQ, they have to learn it. Information is only patterns and if you train your pattern recognition and creativity you can understand anything that our brains can comprehend. There are some limitations that science seems to have discovered, for example some people can at a glance memorize 3 things where others can go up to 5 or even 6 in very rare cases, but it's not clear how it helps or if there is downsides on other areas.
Learning mental capabilities are still not easy and 'gift' could be described as "started very early in life and had enough luck to do it effectively" which would result in many years of effective training without knowing its training.
The best way to look at and understand quantum computing to date- in my opinion! Love this video. Thanks!
I wasn’t originally planning on subscribing but then you said you don’t have to subscribe, and that kind of vibe is exactly what made me subscribe.
Ok besides that point, I really appreciate your information and overview here for quantum computing. I plan to do my masters degree in Q.I.S., so as I’ve been preparing for that this served as an excellent review, plus some new information I didn’t know. I plan to research in an ion trap lab at my university next fall, so that modality along with superconducting qubits seems promising to me, but that’s only based on the very little I know.
I think clarifying early on that the Bloch sphere representation of a qubit is simply that, just a representation compared to the quantum wavefunction was a crucial and helpful point especially for those diving into the field without prior knowledge. Also it’s cool that you worked at dwave and that Qiskit is sponsoring this video, further showing how we need to spread the word and get out as much quality and accurate information as we can. Great work!!
Outstanding as usual! I've always been amazed at just how useful these kind of visualizations are for synthesizing broad information and ideas into real understanding. Personally, even in areas where I already have some depth, seeing a well considered "Map" exposes understanding gaps and reveals the connections between abstract ideas that can be subtle and hard to explain. Your hard work always delivers a few real "light-bulb" moments, "Ah ha! now I see!". Bringing it all together... Thank you good sir.
Love this series so much! Thank you for always putting the effort to educate with such clarity and . Would love a Map of Web 3.0 too!
Web 4.0 will communicate with solar neutrinos... FTL.
@@jan_phd any reference materials??
Web 3.0: “ok, now your NFT will live on the blockchain!” 🙄
One of the best videos out there. Seriously! Thanks a million.
You make me feel like I'm smart for understanding but in reality, you're just really good at explaining xD Brilliantly put and thanks for the video!
1:03 Quantum Computers are not in a huge number of states at the same time, they are in one state, the vector of the wavefunction.
These then get "translated" to the basis vector components (uppon wave function collapse) which we call "classical" states. Its also worth mentioning that the classical state basis components arent classical at all and are also uncertain according to the uncertainty principle. The classical states we call "normal" reality are just an infenetesimally tiny fraction of all the available states. The uncertainty principle isnt weird, our states are.
@@kevin42 the computational basis is just one choice. My point meant to say, that this claim leads to misrepresentarions of qc of the form " qc work by trying all possibilities at once." A balls position is also a 3d vector, but we dont say that the ball is in 3 states at once.
@@kevin42 there's no uncertainty between the computational basis states. They form an orthogonal basis, non orthogonal basis states on the other hand are uncertain
@@Ntropic i didnt mention anything retarding "being in different states at once" for the soul purporse of not causing confusion.
I know now, why my dog tilts his head when I talk to him
A masterpiece of concision and clarity. Bravo!
The best explanation of Quantum Computing so far! As a BSEE graduate from UCI, I was curious and frustrated trying to understand what a quantum computer is. I was especially interested in an explanation in terms of classical computers and all the math I've already learned. Although you had to simplify things a bit, I thought you provided just enough information for me to understand what a quantum computer is and how it relates to a classical computer. In simple terms, there are many potential models that can currently be used. If I understood your explanation correctly and adding my own two cents, I would venture a guess that the search or hope is to eventually find a universal equivalency to which every quantum computing model can be converted. This is probably when a high-level computer programming language can be constructed, which can program any quantum computer, regardless of the model. I might have gotten some things wrong, but that's acceptable to me. Regardless, I feel satisfied that I now grasp the basics of quantum computing. It's the same feeling I had when I first learned what Calculus is!
Honestly, I have a degree in computer science but more than half of this video goes way above my head lmao. I have basic knowledge in quantum physics and have looked into quantum computation but it's all really confusing af.

I'm happy I found this video and found your channel, thank you
Thank you for about the best treatises I have come across of QComputing for a novice like me! Excellent!
"I'll be referring to as classical computers". Next sentence: "...normal computers..." :D
my thoughts exactly :D
Very interesting! (in a time traveler)
This is awesome!!! Timeless Masterpiece, With this I got the best intro into Quantum computing.
literally the best, so happy i found you. thank God ❤️
Pre-liked the video 😉
Looking forward to this one, Dom :))
I think the weather forecasting thing is related to fluid simulation, which is computationally intensive for a classical computer (assuming you want an accurate simulation), but supposedly much less so for a quantum computer.
Amazing video, at least for refreshing concepts. It's been so helpful for a quick review
