ooh. I'll check out the full video. My current work is on the hardware side of quantum computing
As Andrea said in the discussion, there is a ton of work for EE's and others in the quantum computing field.
@@EEVblog For sure. Almost everyone on my team are Electrical Engineers and there are many research areas for EE's. The qubit systems I work on are electron spin based.
@@neomage2021 Why did you choose to do electron spin and not more promising technologies like artificial atoms in superconducting circuits or ion traps?
@@neomage2021 do u work as researcher in University ? Or in some company ?
@neomage2021 I am just starting on EEE UG and I am really interested in Quantum Computing, any advise for someone starting out looking to work in the field?
One of the clearest description of quantum computing I've heard. Have not paid much attention to it from a practical side of engineering, but Morello makes it very easily understood and with as little physics jargon as possible. Making the complex sound simple is a reflection of high expertise. Kudos.
On this side, his shirt is fascinating, it looks like a very densely routed PCB.
"It's either!" ... "IT'S BOTH!!"
28:50 "That would be disappointing" .... "That would be amazing"
@@SamuelFilipesf I didn't click to that the instant he said it!
There is the possibility of both states, not that it's on both states at the same time.
Reminds me of the Lutece twins from Bioshock
@@SuperFinGuy It is in a superposition of both states. So it is actually in both states until measured where the superposition collapses into one or the either.
I strongly recommend watching the whole video, its the best discussion about quantum computing i have heard, in regards to practical science. Very interesting video thanks EEV.
I love this professor! His explanation of how transistors work gave me one of my favorite "aha" moments ever!
This is the first time quantum computing has made any sense to me. Will check out the rest. Thanks.
Im so glade its on the main channel!
Only 25k subs on EEVdiscover, so figured a ton of people on the main channel would want to know about it as well as it's very relevant.
@@EEVblog Holy cow you responded to me, I'm so happy right now!
@@EEVblog Totally worth it. I love those in depth talks. Shouldve been there in the first place in my humble opinion! :)
Great interview! As an electrical engineer it is really interesting to see an explanation of quantum computing from an electrical point of view as most articles analyze it just from a programming or mathematical perspective
hii. listen. actually i wanna ask u that what quantum computing is all about. i mean which engineering field leads to it? pls reply. And is there more programming in quantum computing or not? @maina_daizee is my instagram account, if u want to have a long talk on quantum computing topic, pls text me there. i m a student of electrical engineering with specialization in electronics engineering and software engineering. i m in 1st semester. i would like to get guidance from u as a junior electrical engineer sir. kindly reply.
Thank so much for this fascinating interview with Dr. Morello Dave. Can't wait to get home to watch the whole thing. 👍
Thats amazing and totally unexpected - the world's last Vegas user!
I highly recommend seeing the whole thing! It was great.
The entire talk was fascinating, thanks for talking to Andrea.
WOW, thanks! Most easy to follow quantum computing explaination i have ever heard as of today... And i surely know how complicated it can be to explain complex stuff in simple terms....
The Quantum FFT scared the dickens out of me but the subject is very interesting. I will definitey go and watch the full video, thanks Dave.
I freaking love this guy! Always love his explanations on quantum computing! So glad you sat down with him to help normal people better understand this stuff.
Was that thirty minutes already?! That was super fascinating. I was actually enthralled lol
Watch the whole thing!
@@EEVblog
Lol I did! Right after I made that comment.
entangled* ;)
the best explanation i ever had about entanglement is : "if you have a pair of sock, and you put a sock on the right foor, the other one instantly become the left sock, no matter where it is in the universe"
Wow this is absolutely fascinating! I can actually grasp some of the concept of QC finally. Thanks Dave, thanks Andrea and EEV eryone. x
Really grateful for this interview! Hope to see more cutting edge info.
Love the shirt call-out! I confess I don't remember a whole lot from Morello's lectures at UNSW, but I DO remember his shirts!
A hell of a video! Now that's a professor I'd like to have in the university.
Wooow I thought I was following this but then I lost it, love it, its the nearest explanation I can understand, thank you for at least a glimmer of insight
Andrea Morello is the man!
That was interesting af Dave. Idk why this video doesn't have a million views already
25k views on EEVdiscover so far which is really good for such a niche thing
La sai lunga parecchio Andrea 😉
Thank you for making clear something that is inherently complicated to explain.
Interesting. Going to watch the full interview & subscribe to the other channel. Thanks Dave.
Cheers thaks so much to both of you! Been looking for this explanation for ages, now it makes sense to a plc engineer❤
Add to that is the ending!
13:40 “But the nuclear spin of antimony has a spin of seven half, which means it has eight possible orientations of the spin of the nucleus.” Can someone 3blue1brown that for me, please?
A spin of 7/2 means the spin projection number (i.e. the number of states) ranges from -7/2 to 7/2 in steps of 1: -7/2, -5/2, -3/2, -1/2, 1/2, 3/2, 5/2, 7/2, i.e. 8 states. It's quite analogous to a spin 1/2, which can be in the +1/2 state (spin up) or -1/2 (spin down).
I really like the way the professor thinks, he must be great at teaching. Also Dave got very good questions!
haha love that he pointed out the shirt, i was just admiring it =)
anyone know where to get them? my google fu is failing
So groovy, also would love one
@@WubblyJubblyUK He got it from David Jones!
Said it's discontinue though. Whoever finds it will win The Internet.
I would pay almost anything to get that shirt
I searched for an hour or so, didnt find it anywhere for sale
Thank you for this video! Been majoring in CompE and physics for several years now, and still wondering where it'll take me. I think I've found a cool intersection to explore. :)
It's very cool stuff, worth the speciality.
The way he talks about it you can tell he loves what he does.
This was extremely fascinating and finally made this topic make sense :-D
thanks dave, really cool, i think it's the first time i understand something about this topic. the funny thing is that i am italian in italy and i am listening at an italian who speaks english, lol
Great, great interview!
Should definitely check out photonic computing like the work IBM is doing. It's not quantum computing but is more likely to be realised before quantum computing.
I like the fact that he doesn't tolerate people calling quantum mechanics "weird" or "mysterious". People get intimidated out of learning reasonable concepts, like "imaginary" numbers, "complex" numbers, "convolution", etc. because the names make them sound more difficult than they really are.
That reminds me, I have to do that video on complex numbers.
Thanks For This Dave !!
AWESOME video!
But is it possible for that shirt to be in the state of his ownership and my ownership at the same time?
Adam Hixon... You sound like a socialist now... dont tell me the neo-marxists types are hijacking stem as well?! Lolz
stick to your day job. you're not funny.
@@ypey1 they have always been.
Always.
Man got style, PCB shirt !
@@ypey1 What, you mean like the way your politics tried to hijack my (bad) joke? read: superposition
Hah, watched dilution refrigerator video by Andrea just few days ago :D Thanks for vid!
At some point a quantum computer has to perform arithmetic operations. It would help my understanding to see the equivalent quantum circuit to some simple arithmetic circuit. For example what is the quantum equivalent of a half adder? A full adder?
wow. Before I knew it, the video was over. I might have to go watch the full one now lol
Great Dave , genuinely interesting
Very, very nicely done.
Amazing video loved it
I love the Prof's shirt.
Great interview. I had to search high and low to finally 'get' that the programming methods are like seting up State Machine experiments, in Python. I still haven't figured out HOW to program a Qbits specific algorithm that takes advantage of the super positions.... a d yes, you can 'run' small programs on Quantum computers online. IBM's available and others.
What's the time index in the EEVdiscover video where it continues? Watched this one, trying to continue on the other one, but I'm having trouble finding exactly where to pick it up.
AC voltage goes below 0. all the way to the opposite of it's high. You also need 4 pieces of information for 2 regular bits, as the second position of a binary counter is 3 out of 0-3 or the 4th digit if bit one and 2 are on.
0-15 looks like 1111 filling 4 bits with 16 digits. so on an so forth. AKA 2n
Great video! I'm excited to watch the full interview! While everyone was admiring his shirt, I was admiring that audio equipment XD. Anyone recognize any of it?
I don't know much about quantum computing, but I think the professor has great taste in hi-fi equipment. :)
This is a fantastic talk Dave. If I don't make time for the full version, please blink once for 4 bits. Should I sell all my 0.007 bitcoins?
Your 0.007 bitcoins are safe!
Yeah, but can it run Crysis?
this made me laugh way to much ...
Saw this guy before, and he is on the threshold, of the future of computing!
#thanks EEV 👍 (spin up)
An Aussie quantum computer needs to be called Quantas 😁
Go to your room dad!
Sorry, but that just won't fly.
How does spin up and down have different energy states? @23:53 the professor specifically mentioned high energy state (that enables escaping orbitals), aren't the spin and energy states different topics or is there a trick with the alignment of spins between the device and the electron? If they detect energy difference that enables an electron to escape an atom, wouldn't you relate it to the specific electron orbital where excitation is quantifiable with the jumps. Does the professor explain in the full video why there is a difference of 1.3 K between up and down? Is their device inducing a bias for spin down (or is it intrinsic somehow) and there is some energy leak that enables spin up at all since in order to get a 1.3 K difference it has to get that energy from somewhere?
It does not, until another magnetic field is introduced. So, you set up the experiment, set up the "code" that is the arrangement of q-bits, and set your "result" to be when certain bits are up. If you get an up bit, you know the result was "up". If you get a different result (down, sideways etc) I guess they may have detectors for those orientations, or just take it as a null/zero result?
@@TechyBen I think that its either 1 or nothing taking what the professor described - that they can only detect the "up" since it has enough energy to leave the atom and cause anything detectable with the current technology.
But am I misunderstanding you, that they run a specific arrangement to get any results? So its basically a simulator where the coding is incredibly complex? The complexity lying in the transformation of an equation to be calculable with q-bits.
I LOVE his black shirt!!!!!
Mindblowing!!!
i been to start thinking what missed something at school but now (later on in a video) i know that i never knew about and just been pushing my self to unknown
Thank you M.r
I enjoyed this much better than "The Amp Hour" as I can understand concepts much better when you see his actions.
Yep, agree, the waving hands and finger pointing add a tremendous amount.
@@EEVblog As with q-bits we literally cannot comprehend direction without a visual aid. XD
Love the Smart Guy Red Couch!
i think the electron entering the quantum transistor's drain will be "in like Flynn"
What happened to meason communication to copy quantum based information?
I caught the interview on Amp Hour Podcast
It's better with finger wiggling and hand waving!
muy bien explicado
UNSW represent!
this dude looks so good for his age.
i love his shirt circuitry rather fitting for an interview
So it's a little like core memory modules, from the electronic standpoint?
So turns out that the main working principle of let’s say an MRI (magnetic resonance imaging) could be somewhat used for that purpose (spin turnover due magnetic field)
Very cool! The question on my mind is will quantum computing kill encryption over the internet? Or will standard computing be able to increase encryption to keep up with quantum computing capability?
Watch the full video. Short answer is no, not in any foreseeale timeframe. And yes, it adds to better encryption.
no, it wont. as it is an erroneous interpretation of reality, the only place 'quantum computing' can be realized is simulation, and since that runs on standard computing and is terribly inefficient it will never threaten anything except in the mind of the plebeian dazzled by big words and magic
@@dinf8940 Not really. It has limits and some encryption systems have already been hardened against known types of quantum decryption systems. QM is very much "real", and the computation if gives very much a known (though does have limits and probabilities that lead to failure rates, but so do classical computers fail at times).
Очень интересно! Спасибо!
I feel like he had to dumb everything down so was able to comprehend it. What a genius.
I dont think so, quantum is a joke. The information transfer its like DRAM memory
This reminds me of a tri-state buffers in Digital electronics, that high-z state is neither 1 or 0
@24m00 .... transistor or FET?
I was always wander how the particles are measured for connecting with standard electronics. Also, near absolute zero a 'system' of atoms behave like a single atom and transfer of electrons becomes easy ... That is super conducting
Is it possible to built a cubit in the ISS to reduce noise?
I wish some one else would do anti static field experiments. I am currently doing my own and promising results. Because static can not work in zero degree temperatures there no sticking not conduction of static at those ranges in other words no interference. A static wick would be one example of anti static tech.
im sort of understand and im totally lost , how it works ... or im to old school to get it .... to get an information you need a way to read it and an this point im lost .... how do you know electron spin
The only quantum thing I know is Quantum Leap, I loved that show.
Help of superposition
I think he misspoke at 11:30ish when he said there was 'more' information in two qbits because they describe four states, as this is true for all bits. In two bits I can encode four states: 00, 01, 10, 11. Those states may 'mean' different directions: up/up, down/down, same direction pointing out of the plane, or they can 'mean' numbers: 0, 1, 2, 3, but both is a list of four things. He also says at an 12:53 information density increases as 2^n vs n in a classical computer, which is not the case. If a bit can hold two states, then you can represent at least 2^n things in n bits, otherwise they are not bits. That is the nature of doing things in base-2. The extra information density of qbits comes in entanglement. When you force an entangled qbit to act one way, its entangled qbits take on symmetric behavior (as he stated previously!), allowing you to wire together data with decisions. It would be like having a solid that looked like a cup and saucer, but if you poured a hot liquid in to it, became a cup only, but if you dropped a slice of cake on it, became a plate only. Interfacing with it causes it to instantaneously change its behavior. If you entangle bits, you can have data that adjusts itself as you compute a different part of it, so you only have to do, say, half the work. It would be kind of like computing a long division problem, and as you drew each digit of the quotient you figured out, hazy pencil marks would coalesce elsewhere and by the time you wrote down three digits, the other three digits of the solution just ... appeared.
I''M more than efficiently drunk and this guy made it understandable
This guy has got a sick shirt!
first time this made sense
Why didn't USYD get this guy for their free public talks, because the heap of quantum talks I've seen there were pretty average, ie, too simplified. I like the higher level information, but thankfully he simplifies it enough that I can understand it - some of the medical ones there were over my head -.
"we'll stick with the q-bits, because they are easy"... lmao
Sometimes the less you learn the more you know, because there's less to unlearn.
So a teensy bit of Electrical Engineering Education goes a long way.
Choosing a 3D+T context of an LRC type circuit for modulated time, is the same Principle In-form-ation formulae of superimposed resonances for any and all fractal bubble scaling, aka Quantum Operator Fields Modulation Mechanism Mathematics here-now-forever cause-effect existence, or CCC and AdS/CFT graphic projection-drawing, in an e-Pi-i modulator driven circuit, using elemental LRC/bubble object compositions.

Has the source for the shirt been determined yet?
David Jones. But Andrea said its discontinued. No leads yet.
i saw an speech of Andrea Morello, a some time back .... although you could alter the spin of an electron, being exact 180.0000000000000º, have 8,16,32 atoms on a row to hold binary a value of 8, 16 or 32 bit or whatever, it's basically useless, it doesn't serve anything, you still would needs mechanism as pipelines, ALU's and what not to actually make use of Quantum bits.
you need to put in energy to roll over the electron.
improved credit / debit cards?
Is that what messes up batteries transistor frequency keys , hows it faster then light in the 60s they realy wanted light and thermostatic actuation ... its sounds preety far from using every atom on earth as a buffer on a cloud of universe reflecting quanty fuzzing
It's either! IT'S BOTH. It's either. IT'S BOTH.
what a character
in 10 minutes i give a like to this video then in 20 minutes i want to give another like but i didnt find double like button :(
I need that shirt
Join the queue!
Try photonic computing
I wonder what he thinks about audiophiles?
I also wonder, how do humans know that quantum computing, is the next step in computing? After hearing him, just how practical is it?
