3:15 No, that would be probabilistic computer (still a classical one). Qubits are simultaneously on and off with different probabilities of what you would measure. The whole point of quantum computing is that you are doing the computation on all possible states at the same time. So if you have billion states, classical computer has to evaluate each one by one. If you have quantum computer you manipulate all those billion states at the same time (but you can get only one answer).
🔅 *Great video and info on the different and novel Quantum tech.* I think [eventually] we'll see hybrid chips with different ratios of Classical and Quantum 'horsepower' -- e.g. 80/20 chip real estate, or 40/60 etc. Ratios will vary for different uses like cars, mobile, desktops (office vs gaming), edge deployments, and mainframes/servers. _Great job stepping up the production quality, and keep up the great work reporting tech._ 🙌
That's an interesting idea and I think you're right. Perhaps a quantum AI chip for some types of problems and a classical for others, plus some very clever coding to drive commands to one or the other.

PsiQuantum has been on the market since 2020 if not earlier. The approach to use photons to build a QC is not that new - every quantum hardware platform has its advantages and disadvantages which makes setting good benchmarks so difficult. Personally I love photonic quantum computing because it is the branch I kinda "grew up" with. It is also not the only platform that does not need to be cooled that far. Neutral atoms and trapped ions can also operate at higher temperatures than complete zero. The idea is to calculate the energy of the system you study and compare it to k_bT. If the system's energy is much higher than k_bT it is less affected by thermal fluctuations / thermal noise. For the trapped ions and neutral atoms I am not sure why they don't need to be cooled but for photons it is quite clear. Light waves have much more energy than heat. Heat makes molecules swing and rotate and wriggle around while single photons (depending on the amount of energy) go deep into a molecule and attack the chemical bonds. This makes light a good information carrier in the atmosphere, in space and thus the ultimate ressource for building quantum communication networks. But the same design that goes into quantum networks can be the basis for a rather obscure design of quantum computing called the measurement based design. As far as I know this is what PsiQuantum uses. You can still execute qubits in MBQC like in the gate based model but the model itself is the most complex quantum computing model I have ever seen in my life. Manipulating qubits by measurement and feed forward correction is - well - rather special. The entire decoherence and control problem is switched to the original quantum ressource - the graph state that goes into the process of computing and the computing process itself destroys the computer. From all crazy things I have seen in physics so far MBQC was the moment I thought "Who on earth has such an idea?". The rest of ideas in quantum information is quite straightforward - learning how a qubit works is clear when you know quantum mechanics. Same goes for the quantum circuit model. The adiabatic model is also rather straightforward. But MBQC? I still cheer for the brave people who deal with that part of quantum information.
I think that eventually space-based/orbital classical and quantum computing networks will play an important role in many aspects of our lives. The interplanetary space environment is well suited to the cryogenic temperature requirements of many quantum systems and the cooling requirements of classical systems, allows lower losses for laser (photons, microwaves, radio wave) transmissions, and can be sustainably powered by solar and batteries. Such systems are likely already deployed for military and intelligence community usage. Hopefully, like other aerospace technologies (e.g., GPS, computers), they will eventually benefit humanity as a whole.
I think it'll absolutely filter down to the consumer market. Wasn't there once a forecast that the total global demand for computers was 7? I think technology has a way of surprising us in all the ways it can be applied.
It's doable but not cheap or practical. Space is not cold enough especially this close to the sun. Cooling in space is very different than an earth because there is no air to transfer the heat to. So radiative cooling has to be used and is used on some satellites but cooling needs energy and that means solar panels which means the satellite has to be in the sun. Then you would need to send large amounts a data to and from the satellite wirelessly which is impracticable. The difference between the temperature of space in the vicinity of Earth and the temperature needed to operate a quantum computer is pretty big. Then there is the problem of solar radiation which will definitely cause problems if not shielded to the extreme.
Quantum and classic computing will combine and integrate into one machine. They will seamlessly work together, and their strengths will combine to make truly SUPER computers.
funny how i silently predicted photonic computing to be critical for quantum computing. and now im making two more predictions: 1. photonic computing will make its way into our presonal computers and open up a new path for moore's law pushing the capabilities of our gaming rigs to new levels 2. quantum computing paired with AI will make fusion theoretically viable within the next 10 years, giving us the first commercially used fusion reactor within 25 years
Yeah, it's only a matter of views... sorry, I meant time... till he yells BS! I guarantee that if this video breaks 1M views, he'll do a "debunking" video.
1-08-2024. Look if your going to describe how quantum gate works, start at the block sphere, and a vector, tensor in relation to the sphere is the way quantum gates work
In electronics a device can be built which will down convert ultrasonics into audible sounds to allow you to listen in on birds, bats, and insects. A automobile radar detector of the 1980's could use a circuit to down convert microwaves into audible sound. interestingly at 8:20 the process of driving a photon through a non linear crystal to split the light ray into two beams at lower energy sound to me like a means of creating another type of high energy telescope for outer space, in particular to allow better observation of x-rays and gamma rays. What do you think?
So clearly done! Thank you! Sub'd. Reminds me of getting shown a floor full of IBM computers with the two 12" reels, 1965. 🧙♂️ Has anyone remembered the bug spray?
EXACTLY! That's my thought exactly when I saw PsiQuantum's computer design in Australia. It's going to be a two-building commercial quantum computer. I feel quantum computers are going through the same technology development life cycle that classical computers did in the mid-20th century, and I believe we'll be able to get them to the mass market, especially if we can make qubits with traditional semiconductor manufacturing technologies.
Personal experience - hardware "bugs" are one reason why most servers are found in data centers at about 50-60 degrees F (best) with cold air conditioners and locks, sometimes locking doors that cannot be opened simultaneously, you have to carry your gear into door1, wait 'till it closes and locks, then open the inner door to gain access.
I already saw light as the one of the big futures for room temperature quantum computing or similar computing methods. also how I designed my own computer in around 2016 to 2018 somewhere, but used a much more crude method which is much cheaper and simpler to make and less sensitive to noice, but much lower potential reaction speed, and actually could be more easily seen as a photonic driven analog to a quantum computer with also some of it's own extra added things. also photonic quantum computing methods like the ones used now for how far I knew wheren't there back then, even the basic original ones where new stuf back then, also I surely didn't have the materials to make it anything like how they make such thigns now or to properly sense and process it, so the much more crude way with my self designed R-crown(unpublished due to every invention I tried to publish before being copied and stolen by some random person or company, so if you find something about it online it is probably different, however the component itself looked more like a star, but when warping it around in some dimensions to make a simplified layout of it it looked like a crown) was much better for my use case since it was super cheap to make and as a hobbyist you never really need to run many instructions after eachother to fast since it is just for fun, experimenting, development and testing, and not for stealing data from every person in the world. even though recently I also found a new great potentional for another technique(as in december 2023) even though that one I only tested to create and program quantum effects into normal materials and not yet for computing uses
This could be a game changer. One like fusion working, a station on mars, a general KI or else. For your question what could it be for an impact on our world. I think if a large QC is working, no one needs a personal PC anymore. You just have some kind of TERMINAL to this, and use the power for your needs. Normal PC will ne never be obsolete, there are most cases covered with this, especially gaming, but QC brings out own gamechangers in the future, like you said medicine, logistics, finance and so on.
As long as there are hacks of SS#'s, bank account #'s, names, addresses, phone #'s, there will be independently computing PC's, even if most people call them "cell phones."
Is the advantage of photonic system over trapped ion quantum computing is possiblity of miniaturisation of the chip? May you please make a video on comparison of quantum annealing, trapped ion and photonic quantum computing?
"I think there is a world market for maybe five computers." -- Thomas Watson, president of IBM, 1943 "It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years."" - John von Neumann (circa 1955) I think your prediction that quantum computers will never be a laptop is a little off.
Erwin Schrödinger was wrong, see the cat is an observer and so are the decay bacteria just waiting for it to die. Thus both of them or if the cat dies, the decay bacteria would observe the event and reduce the quantum state vector (collapse the wave function). Not to mention the Universe itself since all elementary particles got quantum entangled at the singularity most call the big bang, thus creating the largest quantum computer imaginable, packing at the very least 3.28 * 10^80 qbits of raw computing power. That number of course corresponds to the number of elementary particles in the known universe. Making it a virtual quantum giga computer, the very computer upon which the Original Observer runs the simulation we perceive as our reality on. That is also the reason for why we must isolate quantum computer from the cosmic 'background noise', which of course isn't noise at all, but the Universe 'talking'.
Very interesting video. I always enjoy your channel. ... But .. ha .. this time, I just had to look up the pronunciation of Qubit. Honestly, I always say it the American English way. But I can deal with it pronounced the British way. Google had links to dozens of websites and dictionaries and "questions" about how to say this word. (Probably does for about any word though.) But as far as I could find, none of those ways sounded quite like the Two Bit da Vinci way. 🙃 But I have old ears and may have to reset my CZcams audio equalizer One bit or maybe Two. ...
Don't forget the lasers silicon photonics use eat up alot energy, so they're not as efficient as you might think at least until there's some sort of gate all around and stacked fin-fet type of innovation in the silicon photonics space. The law of papers tells us to not look at where we are now but to look at what will be in the future. In other words it should get better with time.
What can quantum computers do for me at home browsing the Web? Download 1gb of data instantly? Would it make, say a laptop, faster. Would it replace WiFi or Internet connections? So many questions.
I doubt I will see a quantum Mac Studio anytime soon, certainly not in my remaining lifetime but, we are pretty crafty apes and I have no doubt we will figure it out.
I suspect that this is a very promising path to quantum computing. Photonics, in general, is an amazing discipline and field of study leading from early work that has by now produced numerous Nobel prizes, LED light bulbs, and TV/computer flat screen displays, fiber optics, and so many other technologies. It is an advanced field that America pretty much leads at academic and corporate levels, both in the sciences and the technologies. And to keep that lead, we need all the student interest and talent we can muster in this and other STEM fields. We need support for our universities and politics supporting policies like the CHIP Act as well. PsiQuantum is a California company and Global Foundries is headquartered in New York. And we have Intel and many smaller companies, but presently all the competition comes from the the Far East.
Your beard is epic & I am quite envious... That aside, really interesting video. Learned more than expected. You describing quantum computers as "Another tool to help us solve problems"... helped me a lot. b/c that's something I've constantly pondered about "Quantum computers" is.. "Well what good are they?" If they were helping fusion reactors function, THEN it would make a lot of sense to me. On a side note whatever happened to that Chinese company that released a portable "quantum computer" awhile back? Or did that turn out to be a hoax?
Does it matter if it improves what we can hold in our hand if the interface between what we hold in our hand and it can be made almost so good you wouldn’t even notice?
"A computer in your pocket! A computer is 50-by-30-foot (15-by-9-metre) that will never happen. Never." Quoted by an anonymous computer scientists in 1946.
Hi Ricky, cool video. Can you dive in a little deeper and explain something no one seems to cover in their videos about quantum computers? I think they use the fact that qubits are entangled as part of the algorithm that allows breaking encryption quickly, but I can't find a good explanation of that at the "science communicator" level. People either tell you about superposition and stop there, or I guess there are vids out there that explain it at the PhD level, which is a bit over my head. Thanks.
But, we can live around the quantum computer. We won't need to make them that small. They can become part of our environment unlike a plane That example was a little speculative.
With the photonic approach to quantum computing potentially overcoming scalability issues, how do you see this impacting the feasibility of quantum computers in everyday consumer products?
I could mass-produce quantum computers, based on the genetic code of a specific individual, but it would just be a copy of that person inside of a robot basically. They wouldn't be like sky net or anything... just s regular person in there.
Google Sycamore acheived quantum supremacy in 2019. In 200 seconds, beat the world's fastest supercomputer, Oak Ridge Summit (1st then, 9th today). Requiring 10,000 years for the same task. Summit is the first "exaflop" supercomputer (quintillion operations per second), capable of 3.3 exaflops in mixed-precision calculations.
If its pronouced kwehbit, is your channel pronounced twoohbit? After you got to the 50th use of kwehbit, I had to bail. Man, could've been a great video.

"So, how exactly does it work?" "so, what about this new breakthrough?" Let's wait a few months/years (the company said 2029) to see if this is a real breakthrough and/or if it really works. As long as you can make a video out of it
Does the company you mentioned that is using a photonics approach own key IP and are they publicly traded? How far are they from commercializing this technology?

funny how i silently predicted photonic computing to be critical for quantum computing.
and now im making two more predictions:
1. photonic computing will make its way into our presonal computers and open up a new path for moore's law pushing the capabilities of our gaming rigs to new levels
2. quantum computing paired with AI will make fusion theoretically viable within the next 10 years, giving us the first commercially used fusion reactor within 25 years
Darn, I kept hearing the Thunder foot guy interjecting in my head 😢
Yeah, it's only a matter of views... sorry, I meant time... till he yells BS! I guarantee that if this video breaks 1M views, he'll do a "debunking" video.

Look if your going to describe how quantum gate works, start at the block sphere, and a vector, tensor in relation to the sphere is the way quantum gates work
In electronics a device can be built which will down convert ultrasonics into audible sounds to allow you to listen in on birds, bats, and insects. A automobile radar detector of the 1980's could use a circuit to down convert microwaves into audible sound. interestingly at 8:20 the process of driving a photon through a non linear crystal to split the light ray into two beams at lower energy sound to me like a means of creating another type of high energy telescope for outer space, in particular to allow better observation of x-rays and gamma rays. What do you think?
Love the new graphics, simply awesome!
So clearly done! Thank you! Sub'd.
Reminds me of getting shown a floor full of IBM computers with the two 12" reels, 1965.
🧙♂️ Has anyone remembered the bug spray?
EXACTLY! That's my thought exactly when I saw PsiQuantum's computer design in Australia. It's going to be a two-building commercial quantum computer. I feel quantum computers are going through the same technology development life cycle that classical computers did in the mid-20th century, and I believe we'll be able to get them to the mass market, especially if we can make qubits with traditional semiconductor manufacturing technologies.
@@Israel_Two_Bit it's amazing to watch, again, lol
Personal experience - hardware "bugs" are one reason why most servers are found in data centers at about 50-60 degrees F (best) with cold air conditioners and locks, sometimes locking doors that cannot be opened simultaneously, you have to carry your gear into door1, wait 'till it closes and locks, then open the inner door to gain access.
I already saw light as the one of the big futures for room temperature quantum computing or similar computing methods. also how I designed my own computer in around 2016 to 2018 somewhere, but used a much more crude method which is much cheaper and simpler to make and less sensitive to noice, but much lower potential reaction speed, and actually could be more easily seen as a photonic driven analog to a quantum computer with also some of it's own extra added things.
also photonic quantum computing methods like the ones used now for how far I knew wheren't there back then, even the basic original ones where new stuf back then, also I surely didn't have the materials to make it anything like how they make such thigns now or to properly sense and process it, so the much more crude way with my self designed R-crown(unpublished due to every invention I tried to publish before being copied and stolen by some random person or company, so if you find something about it online it is probably different, however the component itself looked more like a star, but when warping it around in some dimensions to make a simplified layout of it it looked like a crown) was much better for my use case since it was super cheap to make and as a hobbyist you never really need to run many instructions after eachother to fast since it is just for fun, experimenting, development and testing, and not for stealing data from every person in the world.
even though recently I also found a new great potentional for another technique(as in december 2023) even though that one I only tested to create and program quantum effects into normal materials and not yet for computing uses
This could be a game changer. One like fusion working, a station on mars, a general KI or else.
For your question what could it be for an impact on our world. I think if a large QC is working, no one needs a personal PC anymore. You just have some kind of TERMINAL to this, and use the power for your needs. Normal PC will ne never be obsolete, there are most cases covered with this, especially gaming, but QC brings out own gamechangers in the future, like you said medicine, logistics, finance and so on.
As long as there are hacks of SS#'s, bank account #'s, names, addresses, phone #'s, there will be independently computing PC's, even if most people call them "cell phones."
Is the advantage of photonic system over trapped ion quantum computing is possiblity of miniaturisation of the chip? May you please make a video on comparison of quantum annealing, trapped ion and photonic quantum computing?
"I think there is a world market for maybe five computers." -- Thomas Watson, president of IBM, 1943
"It would appear that we have reached the limits of what it is possible to achieve with computer technology, although one should be careful with such statements, as they tend to sound pretty silly in 5 years."" - John von Neumann (circa 1955)
I think your prediction that quantum computers will never be a laptop is a little off.
Erwin Schrödinger was wrong, see the cat is an observer and so are the decay bacteria just waiting for it to die. Thus both of them or if the cat dies, the decay bacteria would observe the event and reduce the quantum state vector (collapse the wave function). Not to mention the Universe itself since all elementary particles got quantum entangled at the singularity most call the big bang, thus creating the largest quantum computer imaginable, packing at the very least 3.28 * 10^80 qbits of raw computing power. That number of course corresponds to the number of elementary particles in the known universe. Making it a virtual quantum giga computer, the very computer upon which the Original Observer runs the simulation we perceive as our reality on. That is also the reason for why we must isolate quantum computer from the cosmic 'background noise', which of course isn't noise at all, but the Universe 'talking'.
kwibit, kwibit I though there was a frog! Well explained though and loved the transport analogy.
Very interesting video. I always enjoy your channel. ... But .. ha .. this time, I just had to look up the pronunciation of Qubit. Honestly, I always say it the American English way. But I can deal with it pronounced the British way. Google had links to dozens of websites and dictionaries and "questions" about how to say this word. (Probably does for about any word though.) But as far as I could find, none of those ways sounded quite like the Two Bit da Vinci way. 🙃 But I have old ears and may have to reset my CZcams audio equalizer One bit or maybe Two. ...
I love the idea of "the Two Bit da Vinci way." This is the way!
Don't forget the lasers silicon photonics use eat up alot energy, so they're not as efficient as you might think at least until there's some sort of gate all around and stacked fin-fet type of innovation in the silicon photonics space. The law of papers tells us to not look at where we are now but to look at what will be in the future. In other words it should get better with time.
What can quantum computers do for me at home browsing the Web? Download 1gb of data instantly? Would it make, say a laptop, faster. Would it replace WiFi or Internet connections? So many questions.
Can.. quantum computers be coupled with analog processors?
Everybody who has demonstrated "quantum superiority" has been proven wrong almost immediately. I don't think quantum computers are the future.
I doubt I will see a quantum Mac Studio anytime soon, certainly not in my remaining lifetime but, we are pretty crafty apes and I have no doubt we will figure it out.
I suspect that this is a very promising path to quantum computing. Photonics, in general, is an amazing discipline and field of study leading from early work that has by now produced numerous Nobel prizes, LED light bulbs, and TV/computer flat screen displays, fiber optics, and so many other technologies. It is an advanced field that America pretty much leads at academic and corporate levels, both in the sciences and the technologies. And to keep that lead, we need all the student interest and talent we can muster in this and other STEM fields. We need support for our universities and politics supporting policies like the CHIP Act as well. PsiQuantum is a California company and Global Foundries is headquartered in New York. And we have Intel and many smaller companies, but presently all the competition comes from the the Far East.
7:49 What? Thats insane and i have to find out why.
Quwibits? Since when? Q-bits is what I have ever heard.
Good video :-)
Your beard is epic & I am quite envious...
That aside, really interesting video. Learned more than expected.
You describing quantum computers as "Another tool to help us solve problems"... helped me a lot.
b/c that's something I've constantly pondered about "Quantum computers" is.. "Well what good are they?"
If they were helping fusion reactors function, THEN it would make a lot of sense to me.
On a side note whatever happened to that Chinese company that released a portable "quantum computer" awhile back? Or did that turn out to be a hoax?
I'll be willing to bet it was vaporware
Nice one Ricky
The audio is a little weird in this video, but very good video nonetheless!
Starting to sound a little like fusion. Any place on the time scale scale you travel to it's only a couple decades away.
Does it matter if it improves what we can hold in our hand if the interface between what we hold in our hand and it can be made almost so good you wouldn’t even notice?
"A computer in your pocket! A computer is 50-by-30-foot (15-by-9-metre) that will never happen. Never." Quoted by an anonymous computer scientists in 1946.
Hi Ricky, cool video. Can you dive in a little deeper and explain something no one seems to cover in their videos about quantum computers? I think they use the fact that qubits are entangled as part of the algorithm that allows breaking encryption quickly, but I can't find a good explanation of that at the "science communicator" level. People either tell you about superposition and stop there, or I guess there are vids out there that explain it at the PhD level, which is a bit over my head. Thanks.
How about the loss of photons leading to inefficiency?
Quantum computing seems to be the only field where you deal with cryptography and chemistry at the same job in the same year 🙂
So you suggest Quantum Computer to calculate about Schrodinger Alien?
Could you run quantum server farms in orbit or on the moon once starship is done? Seems like the cooling would be easier.
But, we can live around the quantum computer. We won't need to make them that small. They can become part of our environment unlike a plane That example was a little speculative.
With the photonic approach to quantum computing potentially overcoming scalability issues, how do you see this impacting the feasibility of quantum computers in everyday consumer products?

haha!
which kind of light does this new design use ? laser, or a incoherent light source of some kind ?
What’s the ticker symbol for the company you are talking about towards the end?
Nobody says "kwibit"
There are already companies making hardware with quantum photonics...
Amazing
Looks kind of like they took the quantum eraser experiment and applied what they learned to computing.
I could mass-produce quantum computers, based on the genetic code of a specific individual, but it would just be a copy of that person inside of a robot basically.
They wouldn't be like sky net or anything... just s regular person in there.
but, imagine if you had the genetic code of a great thinker's mind, such as Einstein
For his 11am filming - I'm just glad he shaved at 8.30
Google Sycamore acheived quantum supremacy in 2019. In 200 seconds, beat the world's fastest supercomputer, Oak Ridge Summit (1st then, 9th today).
Requiring 10,000 years for the same task. Summit is the first "exaflop" supercomputer (quintillion operations per second), capable of 3.3 exaflops in mixed-precision calculations.
Finally I think I understand how a quantum computer arrives at a single result…. through constructive interference
The Two Bit da Vinci is the best on new tech, no matter the pronunciation.......
I’d like quibble about the pronunciation of q-bits
We don't have measurements from "Outer Space" so how can you say that ?
If its pronouced kwehbit, is your channel pronounced twoohbit? After you got to the 50th use of kwehbit, I had to bail. Man, could've been a great video.
Homey, you really should have had someone familiar with basic physics terminology edit this script for you.
What about encryption? Quantum computers excel at that right? How can they be used to protect data?
1:47 when your veiwers are so young they never used MS paint '95...
Good old square paint systems and lack of colour palets XD
all I know is it's highly likely that one of the technologies, AI, photonics, quantum, will lead to breakthrough soon
Is this truly quantum computing, or optical computing?
Two Bit: i had a toy as a little kid where i could put magnetic-shavings of hair & beards, onto a 'bald' drawing, & if my dad wasn't bald, it wouldn't have made any sense ! 😂 (...um, "...as i grow older, i grow younger..." :)

"So, how exactly does it work?" "so, what about this new breakthrough?"
Let's wait a few months/years (the company said 2029) to see if this is a real breakthrough and/or if it really works.
As long as you can make a video out of it
The RGB values go to 255 (11111111), not 256 (100000000).
good eye, :) I was testing you... lol cheers!
Good catch!
Yes, but there are really 256 values, since the 1st value is zero (000000000).
Please make a video about laser beard removal.
Does the company you mentioned that is using a photonics approach own key IP and are they publicly traded? How far are they from commercializing this technology?
