Scaling up to a 1-million qubit quantum computer is already extremely hard from an engineering point of view, as this video nicely illustrates. However, getting those 1 million qubits entangled, and more importantly: keeping them entangled long enough to perform meaningful calculations, that is a challenge of an entirely different magnitude. Sadly, most informational videos on quantum-computing fail to properly address this enormous elephant in the quantum room.
@menno Knol How long do you think it will take for a practical Quantum Computer to be built ? Is 'never' a real option, because of the entanglement issues?
@@ericvosselmans5657 I won't claim to be an expert on the matter in any way. That is one of the reasons I would like to see more videos addressing the decoherence problem for large scale quantum computers. But based on what I think I understand about the subject, I would reckon it will take longer then most of the popular media would like us to believe. Quite a bit longer. A bit like with practical fusion energy.
The enormous elephant is the unescapable truth that quantum theory is but a model of reality. That we can all agree. My point being is that these unusual behaviours such as superposition are not laws of nature but just peculiarities of the mathematical model on which the theory is based. Need I say more?
This video explains such a complex topic in so simple way. This is by far the best quantum computer video i've ever seen. Thank you Anastasiia for your work.
I’m not gonna lie.. trying to comprehend how these electrons spins are controlled and used for computing and can maintain multiple different states at one time.. makes my brain kinda melt.. but it is absolutely fascinating stuff to see that people are making it work. To imagine they can get this scaled down into home or handheld devices in the next.. idk, 50 years? Is just amazing to contemplate what they will be able to achieve
Hi Anastasia! I just wanted to let you know that this is the most informative and well put together video that I have seen on Quantum Computing. Simply fascinating and refreshing. Also your voice and accent are absolutely amazing. Such a unique blend of culture emanating in a harmonious and pleasing tone. I could listen to you talk ALL DAY. Thank you for inspiring me! Also thank you to Dr. Stefano Pellerano for breaking this cmplicated concept down into a digestible and comprehendible format. Bless you.
Thanks for this interesting interview. The algorithms of quantum computers are not easy to imagine due to we are not used to it. The power of this kind of computer is the capability to entangle qubits (to link all their qubits capacity to each other by linear relations) and to keep it away from the classical projection of our univer until quantum computing is completed. When one of the qubit is read, then it determines the state of all the other then we cannot add any other operation to the compute but we have to read all the final state that gave us the solution of the complex operations applied to the qbits system. Each quantum operation can be seen as causality between qubits and it is done into a kind of isolate univer from us that is why we say that it is zero and one at the same time but in reality the value of the isolate qbit are not defined at all for our univer until we touch (read) the qbits ;).
Your voice is so amazing I just can't stand it. If all my teachers in high school had your voice I would have listened to every single thing they said and aced the classes lmao

Quantum computers with a million+ qbits is no joke. It could potentially, or arguably inevitably be the most dangerous invention ever made. It will certainly change the world into something we have never seen before for better or worse.
Anastasi! Wonderful technical video! Excellent content! OBTW, has anyone mentioned today that you are incredibly cute and adorable? (Yes, you are very intellectually talented as well.) Cheers from Texas! 🤠
Anastasi Just looking at all the RF Microwave plumbing its like Art Very Expensive Art but can I say Wonderful 👏 I have my own Microwave Test Equipment & that is massively expensive, I wouldn't guess how much that Copper Gold Microwave Quantum Computer costs, it's Government Research & very high end companies that could ever provide the funding, even Cryogenics to cool that is costly, I feel I am as curious as a Cat 🐈 in Electronics & Microwaves, For your next maybe we could talk about actual programming of FPGAs ? Devices used etc, Philip
Imho, the problem with Quantum computing is fundamental physics, making it's relevant in very limited field of use. It's best use in solving quantum level problems, and it's going to be of limited use in classical world we operate.
That was very informative. I have been playing with programming quantum computers. I have studied quantum mechanics and quantum field theory for 45 years. I have also studied quantum string theory by Michiko Kaku.
Important message is no.3 below, 1. A fridge in 4 Kelvin is also called a fridge?🤔 Putting me inside of it then I immediately become a stone.😆😅 2. By the time he can create a hand-held quantum computer in our hand, Dr. Stefano may be about to time to retire, I guess.😅 So many challenges ahead, but he must be enjoying it. 3. This leads me thinking of an article of a journal I read almost… no, exactly 20 years ago when I was a university student. A female Danish physicist called Lene Hau in Harvard experimented light alighted into sodium atom cloud, by which made the light slowed down to 17 meters per second, and completely stopped afterwards. I also went to Harvard and met a graduate discussing a bit, just a bit, about it around 5 years ago. This led me to think about how a computer can progress in the future. Although these two discoveries look unrelated, but I think these two discoveries can integrate together to develop an commercial advanced technology or computer. I just rechecked this physicist online and Wikipedia, she also had some articles about quantum computing and qubit. I’m sure Dr. Stefano definitely know this physicist as well, maybe you can discuss something about that with him. I think something high-tech similar with the movie inside Star Trek will become true in the future. My work is unrelated to these high-tech for now, otherwise, I do like to research these fields as well.
I don't understand most of what you teach us, but I'm really digging the steampunk vibe of these quantum computers. Feels like time travel is on its way.
@@hateme5010 Among physicists, there is no real doubt that time does really, truly exist. It's a measurable, observable phenomenon. Physicists are just divided a bit on what causes this existence, and what it means to say that it exists.
@@hateme5010 One common misconception spread by an unclear discussion of the nature of relativity and other physics related to time is that time does not, in fact, exist at all. This comes across in a number of areas that are commonly classified as pseudoscience or even mysticism.
@@hateme5010 Time is actually an integral part of the universe. The very linear concept of time is tied into the concept of the Second Law of Thermodynamics, which is seen by many physicists as one of the most important laws in all of physics! Without time as a real property of the universe, the Second Law becomes meaningless.
Thank you. Me too, novice in this subject but like to learn more. Hope you could share in the next video on how silicon is able to achieve qbits? Is it by quantum spin? Also how were these chips fabricated? By lithography too?
@@AnastasiInTech or find complex solution for modern problems like asthma, and pneumonia. People thinking deep going for impossible like time machine when they hear quantum.
Great editing and solid content, it very far in the future for sure, what about the current CPU's a little closer to the ones people might use normally?
Room temperature superconductors seem to be the key to unlocking many different problems in technology today. Superconducting magnets for fusion reactors and radiation shields in space to quantum computing and desalination and so much more.
No. You don't understand how they work. For the average home user they are useless. They are for predictive modelling where there are multiple outcomes. Traditional computing relies on working out KNOWN and GUARANTEED outcomes. That's not what quantum computers do at all.
but this would require a whole new language which i already have a little understanding of. and we all know it's gonna be photonic and organic printed.
Very nicely done, a uniquely pleasant way of presenting complex topics in easily digestible form. Although entangled electron spin strategies are the common current focus, it is the entangled photonic approach which may eventually become the prolific arena of development. There are many (myself included) who see optical computing as the eventual manifestation of the next great paradigm in computation, including optical neural networks, etc. Perhaps a program on this would be interesting?
MIT Technology Review recently had an article titled "Quantum computing has a hype problem". As far as I can see, we are still at the exploratory stage. I have no idea whether it would move beyond a curiosity, to producing something useful, a genuine "killer app". Even if one can expand the number of physical qubits dramatically, there's a question on whether error correction can outrun the noise, esp. when dealing with a large number of entangled qubits. Quantum computing relies on two fundamental properties of quantum mechanics: (1) superposition, (2) entanglement. This could just reflect my ignorance. But the superposition strikes me as almost like an analog problem. And along with this, all the problems that come with analog systems, such as calibration (e.g. the control pulse for setting the superposition state). The other is entanglement. As mentioned in the video, you have to have interconnects between the qubits, to enable this. How would you manage this for a million qubits? What are the effects from different distances, and geometries?
Forget about a million qubits,just to make this work well with 300 would be awesome if they can do it in the next 30 years and that is very optimistic....50 to 75 years is more realistic if ever...
As for calibration, that shouldn't be the biggest problem. Take a look at LIGO/VIRGO to get an idea of the calibration-capacity Humankind has developed. Decoherence of a million-qubit entanglement is by far the bigger problem. From true experts in the field, I would like to hear their opinion on the feasibility of this?
I feel like a lot of the hype about supposed civilian uses is just a cover story to get people to support this ultimate weapon against privacy and freedom.
It's got a massive hype problem. No one seems to understand the purpose of these things, they all spout rubbish about being able to game with them at home 🙄 It's just as bad with companies that tout AI technology. Like AI? Really? NO. I think this stuff should be regulated. How can you claim something is AI when we have nothing even close to a functional AI. We have some impressive learning algorithms. But none of them are even capable of real learning. It drives mew nuts how much stuff gets hyped.
Nice. I have very little idea of how quantum computing work, and I am a low level S/W developer for many years. But some how I still do not think we will really reach quantum supremacy in this century or make useful application with quantum computing.
@@platin2148 The potential for neural networks and AI is also insane. I can only imagine the kind of protein folding calculations we may gain access to.
At one point as you were discussing the potential for quantum computing, you were comparing the number of discrete states that the machine could achieve to the number of atoms or particles in our observable light cone. But, and please correct me if I am wrong here, we can only output by sampling over and over again from that large pool of states to look for the most dominant states. That is the processor could be in a super position across 10^100 states, but your sampling output might only sample 10^10 of them. So, from a informatics perspective, the limitation of quantum computers is not a function of the size of the PROBLEM SPACE they can compute IN, but rather of the size of the SOLUTION SPACE that they can output TO.
A main feature of infamous quantum computing algorithms is to find and highlight the one solution in a gigantic problem space that's otherwise supposed to be impossible to search within the limited size of the universe. So outputting only the strongest value subset is all they need.
Wonder if the hardware could be simplified by operating in space, always in sun shadow, with far less power needed to maintain mK temperatures. This would be a relatively light payload & low cost to orbit, although cosmic rays would be a troubling background, perhaps suppressed with an anti coincidence shield. The main question to me is what problems can you solve that traditional architectures can not. There are clear opportunities to ensure a message has not been read, but what other applications are interesting or useful? Super video, thanks for sharing!
As it requires power, could a solar panel of some type be efficient enough to provide the necessary shade? I could see a comms issue due to maintaining an orbit which keeps the satellite on the dark side of the Earth. I'm no expert on solar panels, engineering, or the climates of space... but it seems like a panel with some type of solar shield/insulation could allow these systems to operate around the globe without need for avoiding the sun.
@@mattallred the mid infra red camera on the James Webb telescope operates at 7 Kelvin & is kept that cold by a cryocooler powered by solar I believe. Quantum computers need milli Kelvin, about 1000 times lower, but in principle your idea can probably be made to work.
Can you imagine cloud Q-bit processing on a 5G network guided by Real A.I.. You asked for ideas, look into nuclear diamond battery or N.D.B. Also interesting would be a segment on 5G and new technologies that will be possible thanks to it's latency.
Well we're decades away from real AI. We haven't even scratched the surface on that one. Although media hype with claims of AI tech would make you think otherwise.
I have a video idea for you. You can make a video for making your own chips. You can make a series of videos for people who want to build cpu architecture from nothing to the finished product.
We are not alone. We are, however, living in a computer simulation. We are simulated. These technical developments are interesting, but ultimately, they are owned by the owner of our reality.
Fascinating. do they have an actual working prototype of this Silicon quantum dot chip? I would imagine setting these bits with an RF transmission line could make cross talk a big problem no? I imagine if they are setting the Qbit state with an RF pulse then they also read the bit by measuring the RF Any specifications? How are the qbits coupled or entangled?
I’m wondering how a megabit QC will help tell us if we’re alone in the universe? (A simple bit of math seems instructive. If intelligent life like ours requires, say, FIVE events with a 1/10^4 probability - e.g. right star, right planet, right distance, needing gas giants in the outer system, needing a large moon for tidal pools, etc - then the odds of intelligent life are 1/10^20. There are only about 10^11 stars in the galaxy, so the odds are good that we’re alone.)
May you can do a video on how to reuse older chip-sets for new roles. I spend a lot of time showing people how you can take older IT systems and give them new roles in today world. Just a thought! We today can get our hands on pretty high end hardware that is being sold on Ebay like sites and people want to learn to do new things with old gear... Thinking out side the box! Keep having fun for I know you are having fun (I think)!
Each of us lives, dependent, and bound by our individual knowledge and our awareness. All that is what we call "reality". However, both knowledge and awareness are equivocal. One’s reality might be another's illusion. We all live inside our own fantasies

a tiny wish regarding names. the people's names are okay, but the companies are sometimes very shortly visible.
Quantum computers with a million+ qbits is no joke. It could potentially, or arguably inevitably be the most dangerous invention ever made. It will certainly change the world into something we have never seen before for better or worse.
Yeah no. Stop watching sci fi movies.
@@lolocaust4967 Well I don't watch many sci fi movies. But I am concerned about encryption. And the markets for starters.
The next 50 years will indeed be very interesting the only sad part about it all is I won't be around to see it.
Anastasi! Wonderful technical video! Excellent content! OBTW, has anyone mentioned today that you are incredibly cute and adorable? (Yes, you are very intellectually talented as well.) Cheers from Texas! 🤠
Anastasi Just looking at all the RF Microwave plumbing its like Art Very Expensive Art but can I say Wonderful 👏
I have my own Microwave Test Equipment & that is massively expensive, I wouldn't guess how much that Copper Gold Microwave Quantum Computer costs, it's Government Research & very high end companies that could ever provide the funding, even Cryogenics to cool that is costly, I feel I am as curious as a Cat 🐈 in Electronics & Microwaves,
For your next maybe we could talk about actual programming of FPGAs ? Devices used etc,
Philip
Imho, the problem with Quantum computing is fundamental physics, making it's relevant in very limited field of use. It's best use in solving quantum level problems, and it's going to be of limited use in classical world we operate.
I'll listen to whatever cuty wishes to discuss.😘
Brain to Brain,interface,presente and futuro.Is a good topic,for a video.
That was very informative. I have been playing with programming quantum computers. I have studied quantum mechanics and quantum field theory for 45 years. I have also studied quantum string theory by Michiko Kaku.
And do you think it will work well with a 300 qubits in the next 30 years?
Important message is no.3 below,
1. A fridge in 4 Kelvin is also called a fridge?🤔 Putting me inside of it then I immediately become a stone.😆😅
2. By the time he can create a hand-held quantum computer in our hand, Dr. Stefano may be about to time to retire, I guess.😅 So many challenges ahead, but he must be enjoying it.
3. This leads me thinking of an article of a journal I read almost… no, exactly 20 years ago when I was a university student. A female Danish physicist called Lene Hau in Harvard experimented light alighted into sodium atom cloud, by which made the light slowed down to 17 meters per second, and completely stopped afterwards. I also went to Harvard and met a graduate discussing a bit, just a bit, about it around 5 years ago. This led me to think about how a computer can progress in the future. Although these two discoveries look unrelated, but I think these two discoveries can integrate together to develop an commercial advanced technology or computer. I just rechecked this physicist online and Wikipedia, she also had some articles about quantum computing and qubit. I’m sure Dr. Stefano definitely know this physicist as well, maybe you can discuss something about that with him. I think something high-tech similar with the movie inside Star Trek will become true in the future. My work is unrelated to these high-tech for now, otherwise, I do like to research these fields as well.
I don't understand most of what you teach us, but I'm really digging the steampunk vibe of these quantum computers. Feels like time travel is on its way.
Time travel is impossible in your life time at least.But who know maybe in 200 years!
@@joannewilson6577 Provided time even exists and isn't a consequence of gravity and entropy.
@@hateme5010 Among physicists, there is no real doubt that time does really, truly exist.
It's a measurable, observable phenomenon.
Physicists are just divided a bit on what causes this existence, and what it means to say that it exists.
@@hateme5010 One common misconception spread by an unclear discussion of the nature of relativity and other physics related to time is that time does not, in fact, exist at all.
This comes across in a number of areas that are commonly classified as pseudoscience or even mysticism.
@@hateme5010 Time is actually an integral part of the universe.
The very linear concept of time is tied into the concept of the Second Law of Thermodynamics, which is seen by many physicists as one of the most important laws in all of physics!
Without time as a real property of the universe, the Second Law becomes meaningless.
ive found your channel by acciedent.... damn your voice is lovely
Anastasi feels computer generated.
Thank you. Me too, novice in this subject but like to learn more. Hope you could share in the next video on how silicon is able to achieve qbits? Is it by quantum spin?
Also how were these chips fabricated? By lithography too?
Yes, the fabrication process is the same as for traditional silicon chips
@@AnastasiInTech thank you
This would break a cryptography in seconds... but I would just use quantumn computer to build myself a second me.
😅
@@AnastasiInTech or find complex solution for modern problems like asthma, and pneumonia. People thinking deep going for impossible like time machine when they hear quantum.
Parallel Quantum Computing, via superposition is the area that intrigues me.
Great editing and solid content, it very far in the future for sure, what about the current CPU's a little closer to the ones people might use normally?
Room temperature superconductors seem to be the key to unlocking many different problems in technology today. Superconducting magnets for fusion reactors and radiation shields in space to quantum computing and desalination and so much more.
At 9:35 you have a picture of a CDC 6600 and you're referring to it as a Cray-1. The 6600 preceded the Cary-1 by about a decade.
once they start making quantum chips that opperate at 40 to 80 degrees like silicon they will REPLACE all silicone within a few years.
No. You don't understand how they work. For the average home user they are useless. They are for predictive modelling where there are multiple outcomes. Traditional computing relies on working out KNOWN and GUARANTEED outcomes. That's not what quantum computers do at all.
but this would require a whole new language which i already have a little understanding of.
and we all know it's gonna be photonic and organic printed.
this video has put my mind in a quantum state … 😂🔥👍🏻😊
Very nicely done, a uniquely pleasant way of presenting complex topics in easily digestible form. Although entangled electron spin strategies are the common current focus, it is the entangled photonic approach which may eventually become the prolific arena of development. There are many (myself included) who see optical computing as the eventual manifestation of the next great paradigm in computation, including optical neural networks, etc. Perhaps a program on this would be interesting?
love your content
1:53 aww what a cutey! those eyes though, what an amazing color!
MIT Technology Review recently had an article titled "Quantum computing has a hype problem". As far as I can see, we are still at the exploratory stage. I have no idea whether it would move beyond a curiosity, to producing something useful, a genuine "killer app".
Even if one can expand the number of physical qubits dramatically, there's a question on whether error correction can outrun the noise, esp. when dealing with a large number of entangled qubits.
Quantum computing relies on two fundamental properties of quantum mechanics: (1) superposition, (2) entanglement.
This could just reflect my ignorance. But the superposition strikes me as almost like an analog problem. And along with this, all the problems that come with analog systems, such as calibration (e.g. the control pulse for setting the superposition state).
The other is entanglement. As mentioned in the video, you have to have interconnects between the qubits, to enable this. How would you manage this for a million qubits? What are the effects from different distances, and geometries?
Forget about a million qubits,just to make this work well with 300 would be awesome if they can do it in the next 30 years and that is very optimistic....50 to 75 years is more realistic if ever...
As for calibration, that shouldn't be the biggest problem. Take a look at LIGO/VIRGO to get an idea of the calibration-capacity Humankind has developed.
Decoherence of a million-qubit entanglement is by far the bigger problem. From true experts in the field, I would like to hear their opinion on the feasibility of this?
I feel like a lot of the hype about supposed civilian uses is just a cover story to get people to support this ultimate weapon against privacy and freedom.
@@johndododoe1411 I feel like you're a tad paranoid.
It's got a massive hype problem. No one seems to understand the purpose of these things, they all spout rubbish about being able to game with them at home 🙄
It's just as bad with companies that tout AI technology. Like AI? Really? NO. I think this stuff should be regulated. How can you claim something is AI when we have nothing even close to a functional AI. We have some impressive learning algorithms. But none of them are even capable of real learning. It drives mew nuts how much stuff gets hyped.
Nice. I have very little idea of how quantum computing work, and I am a low level S/W developer for many years. But some how I still do not think we will really reach quantum supremacy in this century or make useful application with quantum computing.
@@platin2148 The potential for neural networks and AI is also insane. I can only imagine the kind of protein folding calculations we may gain access to.
I think the chip at 2:08 is so beautiful! I wish I could buy their non-functional chips to make jewelry with!
At one point as you were discussing the potential for quantum computing, you were comparing the number of discrete states that the machine could achieve to the number of atoms or particles in our observable light cone. But, and please correct me if I am wrong here, we can only output by sampling over and over again from that large pool of states to look for the most dominant states. That is the processor could be in a super position across 10^100 states, but your sampling output might only sample 10^10 of them. So, from a informatics perspective, the limitation of quantum computers is not a function of the size of the PROBLEM SPACE they can compute IN, but rather of the size of the SOLUTION SPACE that they can output TO.
A main feature of infamous quantum computing algorithms is to find and highlight the one solution in a gigantic problem space that's otherwise supposed to be impossible to search within the limited size of the universe.
So outputting only the strongest value subset is all they need.
Wonder if the hardware could be simplified by operating in space, always in sun shadow, with far less power needed to maintain mK temperatures. This would be a relatively light payload & low cost to orbit, although cosmic rays would be a troubling background, perhaps suppressed with an anti coincidence shield. The main question to me is what problems can you solve that traditional architectures can not. There are clear opportunities to ensure a message has not been read, but what other applications are interesting or useful? Super video, thanks for sharing!
As it requires power, could a solar panel of some type be efficient enough to provide the necessary shade? I could see a comms issue due to maintaining an orbit which keeps the satellite on the dark side of the Earth. I'm no expert on solar panels, engineering, or the climates of space... but it seems like a panel with some type of solar shield/insulation could allow these systems to operate around the globe without need for avoiding the sun.
@@mattallred the mid infra red camera on the James Webb telescope operates at 7 Kelvin & is kept that cold by a cryocooler powered by solar I believe. Quantum computers need milli Kelvin, about 1000 times lower, but in principle your idea can probably be made to work.
Great, thank you!
If you was my teacher at school I would have never missed a class 😍
Me neither, but I wouldn’t have learned anything either….
Can you imagine cloud Q-bit processing on a 5G network guided by Real A.I.. You asked for ideas, look into nuclear diamond battery or N.D.B. Also interesting would be a segment on 5G and new technologies that will be possible thanks to it's latency.
Well we're decades away from real AI. We haven't even scratched the surface on that one. Although media hype with claims of AI tech would make you think otherwise.
I have a video idea for you. You can make a video for making your own chips. You can make a series of videos for people who want to build cpu architecture from nothing to the finished product.
Thank you!
Nice Video !!!
Just getting 50 qubits can make it faster than super computers and 2 million qubits?? Damn technology is scary lol
This seems to be more about storage capacity rather than processing architecture (actual computing). ?
Id like to hear about all the theoretical/plausible application of time crystals including quantum entangled time crystals.
Have you looked into Photonic Quantum Computing?
We are not alone. We are, however, living in a computer simulation. We are simulated. These technical developments are interesting, but ultimately, they are owned by the owner of our reality.
how u know dat
Fascinating. do they have an actual working prototype of this Silicon quantum dot chip? I would imagine setting these bits with an RF transmission line could make cross talk a big problem no? I imagine if they are setting the Qbit state with an RF pulse then they also read the bit by measuring the RF Any specifications?
How are the qbits coupled or entangled?
seen this same exact word for word interview with different actors in 2010
I’m wondering how a megabit QC will help tell us if we’re alone in the universe?
(A simple bit of math seems instructive. If intelligent life like ours requires, say, FIVE events with a 1/10^4 probability - e.g. right star, right planet, right distance, needing gas giants in the outer system, needing a large moon for tidal pools, etc - then the odds of intelligent life are 1/10^20. There are only about 10^11 stars in the galaxy, so the odds are good that we’re alone.)
Using binary levels we can able to find that logic 1 for 5v and 0 for 0v(TTL).
THEN how do they find state of quibit? that means 0 or 1 or 01,10
May you can do a video on how to reuse older chip-sets for new roles. I spend a lot of time showing people how you can take older IT systems and give them new roles in today world. Just a thought! We today can get our hands on pretty high end hardware that is being sold on Ebay like sites and people want to learn to do new things with old gear... Thinking out side the box! Keep having fun for I know you are having fun (I think)!
is quantum computing complex enough to lead to consdciousness?
i love how she says 'chips; :)
In love with your voice
Each of us lives, dependent, and bound by our individual knowledge and our awareness. All that is what we call "reality". However, both knowledge and awareness are equivocal. One’s reality might be another's illusion. We all live inside our own fantasies
