You can tell how knowledgeable he is about the subject by how well he teaches it and how simple he makes everything sound. I can't believe I got so much mental imagery just from watching him waving his fingers. This is epic.

Wow. This covers so many of the mysterious aspects from entanglement to detection and makes them all understandable - without a whiteboard? Dave... Many thanks to you and Andrea for this!
I've been attempting to comprehend QT for decades with little understanding. Andrea Morello explains QT better than anyone I've ever heard. He must be an excellent teacher. The BBC should have him perform a series!
This is the second time I hear a talk covering ee from Andrea Morello, and once again he's spectacularly clear in his explanations. Thanks Dave to have brought him to us.
Years ago I saw an video with him on 2veritasium I could say so many things about the stuff he mention but I fear I we will never see an end about it xD.
@@rickyspanish4792 You commented on my video and I explained you the importance of the video, I think you should edit this comment accordingly. And if you still can't see the value on the video, it's not about the video, the video is based on the most important fact that humans should be made aware. I hope you understand this. Also what you mean by "spam"? I am not profiting by this, I am sharing the truth with the rest to educate and improve the collective culture of humanity, how is that a "spam"? I think you are so used to living in an individualistic and materialistic, selfish profit oriented culture that you see sharing valuable information as "spam". That tells a lot and confirms my point about the loss of connections that I described in the video.
There are few topics / people that make me want to go back to university ('88 degree in computer science and digital electronics). However, Andrea is one of them. His passion for the topic of quantum computing and his ability to explain it are wonderful. There are no doubt some young engineers who, in 20 years, will realize what a wonderful opportunity they had to study with him.
Wow, I can't remember last time I was this hooked all the way through a video. Modern day Richard Feynman in making intrinsically unintuitive concepts imaginable 😍
This is by far the best explanation of QC. What we want is not the ad nauseum throwing about of terms like superposition and entanglement. We want to know the nuts and bolts. The hows and whys. Thank you very much for this, EEVDiscover.
@@VeganSemihCyprus33 Maybe you had an epiphany when you saw it. For me, 1: creationists aren't ready to hear that and are the majority to varying degrees, and 2: it is not relevant to what is happening in western society right now.
Even though i could not comprehend half of it, Prof. Andrea Morello has this gift of bringing the subject closer to me. He has a refreshingly sober point of view, and the ability to look outside the proverbial box... Thank you!
Thanks Dave for putting this together! Never thought I ould watch the whole thing, but here I am still watching... A genius who can communicate well! Feel smarter just for listening!
Apparently, you understand not only quantum physics but quantum computing kick in a balls of R. Feynman who said " I think I can safely say that nobody understands quantum mechanics." You are not dumbo you are next Einstein.
One of my heroes, because he helped me understand this stuff. No one can covey such a complex topic so succinctly. Once you stumble upon Prof Morello, having been confused by every other video on the subject, you’ll finally start to understand! It’s always amazing too when non-native anglophones can do so in better English than most anglophones can!
I only watched the first 25 minutes as I have to go to sleep, but for the first time I feel like I have understood something about quantum mechanics and computing. This guy is so brilliant at explaining things. Thanks you so much for this video. Will be watching the rest soon!
I have zero physics background and yet I feel like I understood like at least 50% of what was said. Mr Morello is such a good explainer that even a layman like me can understand the gist of quantum mechanics.
It's a bit annoying how often the interviewer is speaking over the interviewee. Like that kid in class who is a bit to eager to prove how much he already knows about the lesson being discussed
43:24 made me realize how we write code for all GSM/RF modules who IC's have proprietary datasheets. Wonderful Explanation on Quantum Computer. Thanks for sharing.✨✨✨ Cheers
This is great Dave! I'm glad you put the whole thing up, it was super interesting. I would love to see a follow up conversation in a year or two. Honestly if there were 2 more hours of this I'd queue it up right now!
Nice talk, very engaging. Twenty minutes into the video i noticed the guy's shirt has circuit traces on it, was a bit harder to concentrate after that.
This is pure gold Dave. Have been waiting to hear much more from Mr. Morello as I have followed his work for years. He really know how to explain things in a clear manner. Then I saw this video of him showing up in my feed, and it's 1 hour and 45 minutes(!). I think, Wow! Cool. Then I see YOU as the interviewer, and it's the best of two worlds!! Mark his words in the end about you really asking good questions. You both do really great in this video. So interesting. But I still not understand how a quantum computer computes. What in the quantum world does the qbits tap into, to decide what an answer should be? I can somewhat understand that it can only do certain specific things very fast. I not think we will not quite understand this, until we merge these technologies with the theories of Hammerhoff/Penrose. Then we will se quantum leaps in AI, and start to understand our real conciousness.
Example- the Intel Core i7 processor is a bank of 8 processors. 1 processor is used to unite the other 7 processors into what is effectively 7 Computer brains dividing the work load and working in unison to solve. Quantum computing is the same concept of adding parallel computing on the bits ( 1s and 0s) them selves by adding additional bit representatives. Yes this is reinventing the wheel and Yes, unless you are processing fractal equations, there really is no point, because there are MUCH CHEAPER AND EASIER methods. The cooling systems needed for these machines alone, make them... not useful... in most applications. Like owning a Ferrari...
I am no expert on this, at all, but I've been able to gather this from off handed searches and limited understanding: Quantum computers utilize the weirdness of quantum mechanics to process data. Things like entanglement and superposition can be applied to qbits as variables to set up computations. You put the system into very specific quantum states, let it do its quantum things, then measure the system. The big difference from computers as we know them is that once you take that measurement, the entire system snaps into a classical state. No more superpositions and entangled particles. Just ones and zeroes. What you are left with is a set of binary values that can be read. And if you've initialized the quantum system right, you will find certain sets of states will correlate to answers you are looking for (like which values of a hundred variables are optimal for an airplane design, and which two giant prime numbers best multiply into a huge number). Quantum mechanics is all about probabilities. So using That system in a computer will make tasks that are intrinsically probabilistic more accessible. Decryption and optimization are among the chief uses for such a system. Does that clarify things a bit?
-FINALLY!!.. Someone can explain Quantum Computing BY COMPARING the logical process we knew in classical computing first, and then how it can be converted or translated to a "Quantum level computing or "QBITS-LOGIC".. it was WELL EXPLAINED, DETAILED, AND SPECIFIC!👍😁 -I've almost lost interest on this technology because I cannot grasp its mechanism in terms of logics in computing before, until this guy enlightens me. Thank you sir!👍😁 -The interviewer also played vital role to make the topic comprehensible and "on track", especially for those who are not engineers.👍😁
I've had to re-watch this a few times and it is one of the most interesting and educational videos I've seen in years. We've come a long way from when I got my EE or Physics degrees, so I can only imagine a class or project with this person. Thank you both so much for this!
I just have a discussion on Qbits in ion traps. I came immediately to...but...and Andrea Morello....came back to this Video again...That man is extraordinarry fantastic, just a stellar man.
There is just one issue with using the Schrodinger equation for financial arbitrage : particles in physics are perfectly random and follow a normal distribution, the logreturns or log(price) of financial assets aren't normally distributed and the distribution is fat tailed. The Black-Scholes model inspired from the partial diff equation of heat dissipation used to price financial derivatives (options) misprices completely risk by using Normal Distribution and underestimates extreme events. Very interesting video tks !
56:00 I'm reminded of orthonormalization in 3D rendering. Every time you rotate using matrices, you induce a little bit of floating point error because of the hardware accuracy limitation so the axes that should be orthonormal end up being slightly askew. So every time you rotate, you make sure your basis axes are perpendicular to each other by picking an axis and forcing the others to align to it. Over time, this prevents the "warping" of the basis axes in the same way it seems like the "clocks" of the quantum buts would want to misalign.
people watch movies.l, I rather watch this. The deeper they get into details the better... it hurts a bit when he says "for the purpose of this discussion we can forget about it"... then I'm like: noooo, tell us all about it!!!! haha, anyway, I really enjoy this kind of contents.. keep them comming!!!! 10/10.. oh and btw, it's great when the interviewer knows the topic like you do, and asks or comments the kind of things one would ask or comment if had the oportunity... great job!!!
One of the best more in depth talks I have ever seen on the subject. Really well explained by mr Morello but also with the correct questions at the right time from the interviewer. A must see for all those interested in the subject.
Wow a ton of interesting information. Would love to be in his lab for a day, watching this in operation would be amazing! I bet you were excited to be able to spend this time with Andrea.
This is first time someone is saying that "QM is logical" and not like most people who try to create a suspense around it e.g. "QM is counterintuitive", " QM is mystry", etc. etc. Really logical and nice dive in Quantum computing by Andrea.
This is a great description of some of the fundamentals of quantum computing. But one essential question is not specifically answered: Which aspect of QC concepts or technology is it that makes it “better” or more capable than classical computing? For example, what aspect of QC is it that allows it to factor a prime number quicker? Unfortunately it’s not sufficient to just answer this question by saying “it’s the superposition”, or “it’s the entanglement”. You might as well say “it’s the magic”. So, if it is superposition, then what are the engineering mechanisms that allow the measuring or harvesting of advantages of superposition? If QC is faster if doing an operation, where does the “speed” come from? Or if QC requires a fewer number of steps to do a task, where does that advantage come from? For example, in the phone book search example, how does the element (or mechanism) that shows the highest probability for the desired solution do that? Another video will be very helpful. Thank you.
as a physics student specializing in quantum computation... this is just an incredible explanation!! I've watched many videos of Prof. Morello and it's quite fascinating every time.
really? what "explanation"? all I heard was him simply "saying" that an electron can be spin up AND spin down "simultaneously", ( anyone can say that, that's at best a description, not an "explanation" ) why do you think what he said was an "incredible explanation!! "
What a wonderful presentation of the topic! Super-quantum super-thank you, Andera is one of the "chosen ones", the most qualified specialists on quantum computing on the planet!
I'm so appreciative of this interview and what a great teacher professor Morello is, as well as the great questions and enthusiasm of the interviewer. Thank you for posting this, I've watched it about a dozen times and learn something new every time.
Such a shame that most other videos on this topic seems to assume that viewers are dumb, this is litterally the only video I could find that explains quantum computing so well and with such detail. Thank you both
This is the best explanation on quantum computing ive ever seen! Ive been following it for years but most talks or interviews left me with more questions and confusion. Dave is asking the right questions (for someone like me) and the professor answers all of them in a fantastic way.
really? so now you can understand how a spin can be pointing up and pointing down at the same time? do please enlighten the rest of us because Morello certainly didn't
When even a grumpy old electronic tech/network admin like me understands, its a job well done, thanks to you both for a fascinating discussion, so well explained.
he didn't "explain" anything ! he just "asserted" that it was possible for a spin to be pointing in two opposite directions at the same time, which is obviously false!
Wonderful conversation. Long conversations with smart or dedicated people make a huge difference in education in my experience, and give a completely different perpective than planned lectures of books.
Thanks for posting this in depth talk, I admire this guy for explaining refrigeration cooling at quantum level. And now this! Please ask him to show his lab and experiments sometime please.
Extreemly informative and condensed matrix of information about what is being done in this field of science and technology and some interesting predictions. I think that Andrea is right about scaling limit to be related to max achievable quantum information density. This kind of limit could be the kind of fuse for foreseeable future to prevent human beings from being able to get knowlage of something that could give them enough power to destroy the whole universe. I believe there should be such fuse to protect our universe.
