It's the first time in my life I understand what a genius is talking about. That guy has a real talent for explaining complex subjects and making it accessible to regular people.
Someone should put him in a room with people less knowledgeable on the topic, and then pay him to explain it to them. I think it could help a lot of people get smarter.
"If you can't explain it simply, you don't understand it well enough (Albert Einstein)". This guy is the physical embodiment of that quote. He understands his area of research extremely well to the point where he can convey the information as an abstract concept that a group of people who are not a PHD in math and physics could still understand it. He's not just repeating equations from a text book, he's making this his own.
He is also obviously very passionate about his work, and this is something I always tell younger engineers--find something you're passionate about. I've been in engineering a couple of decades and I've seen a lot of engineers who chase the money, and hey I can't blame anyone--we all would like more money... but doing something you really believe in is rewarding in a completely different (and I feel even better) way.
Haircut and nano beard under the lower lip is probably quantic too… 😅
Yeah same to me, but when i then look into another key feature of a qubit "Entanglement" that two or more quantum particles can be linked toghether even by a large distanse, it all became fuzzy again for me :-)
Andrea Morello is such a character and you can feel his excitement about his research. Great video Dave!
OK, that's the "coolest" use for an SMD 1.5k resistor I've ever heard!
Here is an example of a great scientific communicator able to explain the technology he is clearly passionate about. I envy his students!
This deserves at least 10M views.
why
@@ugetridofit555 timer joke.
No - hopefully not, but not because it is bad, but instead is so amazing good - it would be an insult against Andrea Morello and the work of Dave.
Views over a few hundred thousand is more a hint for bad loud screaming "trash" or "i am so better than you", that ugly " look how stupied this... is" Videos, that simple and dangerous " political" solutions videos and that millions of simple hate or "cute cats and kids" videos.
This channel and its viewers are not the "normal" ...youtubewatchers...
@@Jumansa19 Or more concisely ... shit floats.
This was FASCINATING. He's so incredibly pleasant to listen to. Thank you so much for making this.
There are not enough superlatives. He's so fluent in this quantum thing subject that I have the impression I could understand what he says. Thank you Professor and thank you Dave, this is one of the greatest video's on the subject out there. Actually, no, it IS the GREATEST.
THIS is exactly the kinds of explanations I have been looking for on quantum computers !
Thank you !
I know right? Usually it's just a bunch of hand waving "well it's both at the same time because quantum."
Best video ever!! You don't see many videos deep diving into quantum computing as this one does. This it's a whole lecture itself. Congratulations Dave!
My god, I finaly get it! Now I understand how the machine works the rest is self explanatory. Truly fascinating and a credit to yourself and professor Morello that you were able to convey such a complex subject in such a simple and easily understood manner. I feel so much smarter after that.
This is the best explanation on quantum computers I have ever seen. It is a big pleasure watching all the complex details so well explained. Thank you for doing it!
This is an absolutely fascinating topic, and a brilliant communicator delivering it in an understandable way. He really does lay things out in a very straightforward and comprehensible way, especially when dealing with highly abstract and esoteric concepts that people typically misexplain or oversimplify. I would happily watch many more hours of this gentleman describing concepts.
I put off watching this video for quite a while because, well, 1 1/2 hours. But since watching it, I have to say this was one of the most amazing videos I've seen. I learned a lot. What's really fascinating is that Dave kept bombarding Professor Morello with tons of 'really specific' difficult questions, and without skipping a beat, he had an instant and easily understandable answer to all of them. He's also given me an appreciation for why this stuff is so difficult and why quantum computers have yet to become mainstream.
I also left it in the back burner for a bit, but oh boy, this was an awesome watch. When this man says he is a world expert in something, after this video, I fricken believe him...
The insightful understanding of Professor Morello is profound and his communication in such a mix of complex subjects is brilliant - in fact so good that even I absorbed parts of it, and I was also impressed by your intelligent questions Dave. IMHO, Quantum physics and computation are such a foundation to all things, that currently we have little/no idea where they are going to take us.
This guy makes quantum mechanics seem so simple, love it
Thank you and Prof. Morello, emphatically, for this video; your channel is the only place where I can get any tangible, real-life information about quantum computing systems. Great stuff.
This is why I LOVE Andrea Morello. Thank you for this video
Mr morello is a goddamn genius! He explains stuff with such accuracy and simplicity
Really enjoyed this, could listen to Prof. Morello all day..
*Absolutely loved this video* ❤❤
I would really like to see more of this, but also about other topics/fields.
Thanks to Dave and Andrea for taking the time to make this video together ❤
This was absolutely a mind blowing video! I actually learned quite a bit!
That constant noise would drive me mad.
Excellent video love the level of detail thank you so much for the guests time and eev blog!!!
No way! Andrea Morello is alive and well! I was waiting to see him for the last 10 years!
As a Chemist I only can say wow! How fascinating this topic is. Very good explanations. I am used to general quantum chemistry, but I really need to look deeper into this quantum computing thing. Awesome. I love it.
What an absolute thrill to have a tour of each component.
probably one of the best quantum computing videos so far on youtube
Fantastic video. I spent a number of summers in the late 80s working as a student engineer on a 6inch analogue fabrication line for National Semiconductor. Brought back memories especially the corridor of helium pumps.
I clicked on the video to save it in my history to watch later but 40 min in now.. Outstanding video!
Great stuff EEVblog! Dr Morello is a pure genius. I discovered his brilliance 10 years ago when Veritsium did a series of videos about quantum theory featuring Dr Morello which showcased his excellent teaching skills. Even though he has a deep theoretical knowledge of he physics he also connects this to the realworld engineering and practically.
Fascinating video! I did quantum computing as part of a degree and this really helped visualize the real world functioning of it. Andrea Morello has an excellent ability to communicate such complex subject.
Thank you Dave for these informative videos, you're the best EE-CS channel on youtube
So jealous of his students! What a great educator and what an amazing video. Thanks!
I usually watch all videos at x2... had to slow this one down and take it in. Amazing and thanks for this gem.
Bloody Brilliant presentation mate! I learnt more and had stuff I knew explained properly in that 1-1/2 hr than I did in years reading! Thank you very much! Keep talking to Andrea!
this is so freaking cool!!! I really love that the veil has been lifted on this sort of stuff.
Thanks for this one Dave - and Andrea! This is fascinating to the near absolute zero core.
That was awesome. Can't wait for part two.
Excellent info! More topics, please !
Truly Inspiring!
Thanks! Very comprehensive explanation, love all the physics involved in these machines
Wow! Thank you Dave and Andrea for sharing this knowledge. It is very exciting and enlightening!
Brilliant stuff. Thanks, Dave.
This was such an amazing watch! Thank you and Professor Morello so much for this upload. Such an interesting interview!
So much insight given and so approachably explained!
Fantastic video, thank you for sharing. Andrea is so smart he makes me feel like I know what's going on....
I had a class in quantum mechanics as part of my EE degree, I learned more from TH-cam than I did from my professor.
Amazing interview Dave!
Really well explained. Good job Dave
I worked in a research wafer fab for 13 years and continued working on High vacuum systems for years more after that with TMP's / cryopumping and a lot more ... I really found this video fascinating ... thanks Dave.
What a cool guy explaining quantum physics! I don't have enough enough thumbs ... Thank you for part 1.
Thank you for such an understandable explanation.
Imagine being the one atom of 10^80 in the universe and having this fella single you out and micromanage who you entangle with
that's top-level mansplaining from this scientist. Terrible... ¬¬
What a great video! Love this so far.
my oh my, still remember the moment sitting in his class, always my fav elec lecturer even 8 years after graduation.
Finally a thourough explanation of the machine! (Please hold the video camera steady)
Thank you for this absolutely amazing video Dave, and thank you for the absolutely beautiful explanations Andrea! It's a perfect mix of popular science and advanced discussions. I actually learned a lot. Hope you continue this series, dream team!
Completely impressed with the professor.
Maybe the best video on yt, Andrea is great. Daje Andre’!!!
Thank you, very educational. 👍
Very nice video, looking at the engineering aspects.
Excellent video. I've been looking for an in depth video of a quantum computer. The good look at all the hardware/explanations was awesome!!! Nice explanations of how it works too.
Im amazed by the human hability to create things and how the knowledge of many people materializes in the creation
Nice work. Working on development of an instrument is hard, and when it is such a niche category like this, it is even harder. 👏
IMPRESSIVE Introduction of Morello Quantum Antimony Style
I really admire the years of study and experimentation that were condensed in this video, he surely knows all the quirks and details that go on inside the quantum computer, really bleeding edge of research right there.
This was quite fascinating. Like a numberphile episode
I feel I'm ready for that Quantum exam now! 😂
This is fantastic!
Love this Science EE mix! Thx Dave
Damnn this was so intriguing, one of the best videos I have watched on this channel. From start to finish in one go, every second of it. Didn't even feel like a 1.5 hrs long video, felt like watching a movie.
Prof. Morello really has a way of explaining things in a logical manner that is easy to grasp
For years I have wondered How they start current flow in a superconducting coil. It is so ingeniously simple. I know that was not the main point of the video but I thought it was fascinating to learn.
Great update with wonderful Andrea Morello! You asked yourself relevant questions that helped understand a little bit more - depending on your background in electrical/electronic knowledge. Andrea's explanations are so valuable and erase confusion. Very instructive 90 minutes. Thank you very much. What I appreciate the most: quantum computers do need very very good classical computers to reduce errors. Finally the best and useful point of this stunning post. Btw Aussie research has nothing to envy other nations'. Good news Aussies!
Wow...words fail me. Thx for this!
The focus hunting was driving me insane haha, was begging for some manual focus. Or a higher f-stop. Camera stuff aside, WOW this is super interesting. Thanks for sharing this with us!
Fascinating video! Professor Andrea Morello is clearly one of the few people globally who are inventing and moving the entire field of quantum computing forward.
So his setup has 4 qbits, 8 output possibilities, and requires 7 phase coherent ~40 GHz signals to use. He says we need 100-1000 really well behaved qbits to do something practical like medicine molecular research. Each well behaved qbit will have some sort of triple redundancy, so either 1000 raw qbits -> 333 usable qbits, of for 1000 usable qbits we need 3000 qbits. I don’t quite catch which it would be. Each of those will need its own 40 GHz x the number of levels per… plus all the classical electronics like FPGAs and compute and storage….. a true functional quantum computer like that would be massive!
Seeing how stable and repeatable his silicon based setup is, I can see this actually being possible in the not too distant future! It seems like one of the remaining challenges is designing and building the system around all the qbits. RF, power, FPGAs, refrigeration, magnets, etc.
When you understand your field - you can explain it with simple language. This guy is the Genius in his area :)
if only i had Andrea as a teacher at school
This video was awesome!
Thank you so much
So interesting when you think about all the tricks scientists have to come up with to overcome different problems. Just to come up with such a simple solution for shorting the superconducting magnet coil, using a second superconductor as a "circuit breaker" by heating it above superconducting temperature. So simple yet so effective.
I may have to go back to uni ... what an awesome prof.
Very high-density and comprehensible knowledge. Mostly about HVAC science, of course, at lsast at first. But I'd love to take a course from Prof. Morello.
Fantastic video!
That was awesome and having a semiconductor background I 'got' a lot of it for the first time so kudos Andrea for his explanations. What I cant fathom is how any of this converts to putting in a calculation and getting a result out that is useful, still one of the best I've ever seen though would love to have seen more like the Ion Implanter for instance....cheers !!
It doesn't translate into anything sensible. You have to figure out a trick, every time. It's not general purpose in the slightest. Quantum computers extract money from investors, nothing more. Nothing has ever been done with a quantum computer. Literally nothing, ever.
That is how I feel about it ! :)@@douggale5962
Extremly informative and as always Morello is a diamond to watch as he pours out his practical and theoretical experience and knowledge. He could be honoured with a better thumbnail though :)
I remember watching a video a couple years ago of this guy explaining all this before they even had a physical computer
Great interview very interesting
The amount of fields these things touch in doing just tests is incredible. if we could speed up time to peek at what things would in 90 years..
3rd decade of AMAZIN quantum computers and very oddly they do stuff but they don't do stuff.
Excelent proffession to get into, no results required.
More talk about refrigeration please.
One of the best videos on YT
Morello is a superstar
Interesting video. I always wondered how they measured temperature for Quantum Computers and wondered what kind of thermometers they used. Instead the thermometer is a resistor, and you measure the resistance.
Great video to watch too
great video!
Great video
All of this will be looked back on in history, as core rope memory from the Apollo missions looks to us today.
That guy is brilliant. Big picture thinking.
Amazing
Grande Andrea 👏
54:30 - this reminds me of "folding at home". IDK if it's still a thing but it makes me see how classical computing just can't really give you specific answers beyond brute forced simulations to see what comes out the other side
Very interesting video thank you
nice work
