Fantastic Chris. Finally someone everyone can trust has simplified it.

[@OPIXdotWORLD]

@@marcdraco2189 please explain quantum entanglement...

[@marcdraco2189]

@@OPIXdotWORLD You mean having two quanta from the same particle that exist in such a way that anything acting on one effects the other, even if they are not physically close to each other in our concept of three-dimensional space? Naturally that's a massive oversimplification and there are even suggestions that two quanta can be entangled even if they don't exist in the same moment (so to speak). That stuff is outside my specialist areas of interest. I write about classical computing, agricultural and evolutionary biology and food science. Wikipedia has loads on it written by people far more entangled with this area than I am. (Boom, boom!)

[@marcdraco2189]

@@vardekpetrovic9716 Sure, I don't profess to be an expert - particularly in physics. I love the joke that "when you believe you understand quantum effects, you don't". I'm familiar with the multi-dimensional idea of time/space. Didn't we get to something over 10 dimensions in the math? I see there are also 26+ in some papers but since I have trouble with quaternions, I'll gave those a miss.

[@marcdraco2189]

@@vardekpetrovic9716 Quantum physics is weird, but then again, so is traditional physics in some areas. Most of us still believe that electrons travel through copper (and other conductors) but now we're waking to the idea that the energy is carried in fields. If you can hear that creaking where you are, that's my poor brain trying to wave a white flag of surrender. I think in context, what we can say is that quantum computers won't be able to run Crysis any time soon, but they will likely be able to decrypt your encrypted messages. Which is more concerning.

[@whatsupbudbud]

Very unlikely for the sole reason that quantum computing works nothing like a binary computer. There needs to be a middleware interface which interprets the data. So it makes perfect sense that computing time on quantum computers will be pay as you go services which you access online much like AI services are becoming now.

🤣🤣🤣 That seems a lot easier to understand... 😊😊😊

[@Dyslexic-Artist-Theory-on-Time]

One way to think of quantum physics is that the wave particle duality of light and matter in the form of electrons is forming a blank canvas for us (atoms) to interact with; we have waves over a period of time and particles as an uncertain future unfolds. The mathematics of quantum mechanics represents the physics of time with classical physics represents processes over a ‘period of time’ as in Newton's differential equations. In this theory the mathematics of quantum mechanics represents geometry, the Planck Constant ħ=h/2π is linked to 2π circular geometry representing a two dimensional aspect of 4π spherical three-dimensional geometry. We have to square the wave function Ψ² representing the radius being squared r² because the process is relative to the two-dimensional spherical 4π surface. We then see 4π in Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π representing our probabilistic temporal three dimensions life. The charge of the electron e² and the speed of light c² are both squared for the same geometrical reason. We have this concept because the electromagnetic force forms a continuous exchange of energy forming what we experience as time. The spontaneous absorption and emission of light photon ∆E=hf energy is forming potential photon energy into the kinetic energy of electrons. Kinetic Eₖ=½mv² energy is the energy of what is actually happening. An uncertain probabilistic future is continuously coming into existence with the exchange of photon energy.

[@jose.inestroza]

[@poetryflynn3712]

I think a greatly overlooked skepticism of Quantum Computing is the idea everyone will have a Quantum Computer. Personally, I believe we will never be able to bring individual parts a PC to be cold enough to run a Quantum Processor. It's much, much more likely quantum processors will be locked in server bays behind corporate doors - hence so much investment from Google or Microsoft. Quantum Computers will be an extension to Cloud Computing. Superconduction has been studied extensively for well over a century, it's unlikely the problem will be solved.

What really interests me is if ECMWF or UKMO are planning or already in development of using quantum computers for their weather forecast models. I know, the forecasts will always be as good as the data we provide the models, which is finite, but I could imagine that quantum computers would be able to model the quickly changing weather phenomena much more accurate and quicker than the conventional numeric models we have in use today. This year, we can see the GFS model struggling especially with forecast in central Europe, where ECMWF and ICON were much more accurate. I'd like to hear if there are efforts being made for weather models in quantum computing. I couldn't find information for this myself.

That's a lot of research (and separating of technical grain from marketing chaff) on a technology that seems obscure at the moment, but might become important very quickly. Thanks for doing it for us. Two questions spring to mind immediately. One is the OS implications; will these things require a speciaised OS, or function as some sort of peripheral managed by a conventional one? The second is "What's the origin and implication of those odd multiples of chip counts, processors, &c?" It's easy to explain conventional computing multiples as binary powers, but the quantum ones don't fit any obvious pattern. The multi-processor, message-passing architectures proposed are definite echoes of simiar ideas proposed in the early days of conventional computing. Will they succeed this time?

[@microdesigns2000]

When I was I kid, my grandparents heard I had an interest in electronics. They found an old "integrated circuit experimenters kit" and gave it to me. It appeared very outdated to me because I understood integrated circuits to be 74xx TTL logic chips, and had no interest in analog circuitry at the time. But it was very interesting just the same. The kit had a large (3x2in) ceramic rectangle upon which there were two smaller ceramic squares, upon which were various miniature resistors and capacitors and two to three transistors each. Someone had constructed these "integrated circuits" as building blocks to something bigger. My ten-year-old mind didn't quite understand all of it, being some kind of operational amplifier. But I did understand the idea of miniaturization. As a gift, I eventually received a Radio Shack 150-in-one electronics kit, increasing my love for the seemingly endless possibilities of electronics and computers. This realm of quantum computing seems every bit as nebulous as electronics was during the dawn of the digital age. I know quantum experimenting can be done online. But I feel like there ought to be some crude little quantum computing experimenters kit that can be given to children. Surely that would be a mind-bending gift.

[@ExplainingComputers]

What a great post. I had I think a 50-in-one Radio Shack kit, and spent hours putting wires into those springs to build stuff! :) I can imagine a children's kit for creating quantum circuits that reaches out to the cloud to run the results. :)

I can't help but think that it's got another 20 years to go before anyone can offer a system that is stable enough, reliable enough and large enough to be useful as error correction must almost square with the number of qbits in a system. Once they have access to those systems it's going to be a race to use them to model new materials for better quantum chips it's going to be an exponential curve of improvement. 20 years in the future Seagate drives still be shit!

[@ExplainingComputers]

When a qubit is observed it collapses to a "1" or "0". But the probability it will be "1" or "0" on observation is what gives us the infinite range of values (0.0000001.... to .999999999....). And we use observed qubits to measure what is going on with the non-observed (and hence non-collapsed) ones. It it mind bending stuff.

[@timb.4902]

A fantastic and thorough video, as always! Thank you. I happen to work with computers on the software side and still remember how excited all the people in the mass media were about the 64-bit CPUs, or 5G technology. Many "wonders" have been ascribed to these developments, and I always wondered "why" (in disbelief)? The 64-bit computing was such an overused buzzword that (apart from the larger addressable memory space access without having to resort to the pesky "segment-switching business", and a larger integer size) didn't seem to offer much to an experienced programmer, or 5G was bound to "change the World" (and then COVID-19 rained on its parade). The question remains: how "exactly" is Quantum Computing faster then the conventional one??

[@ExplainingComputers]

Quantum is more powerful than conventional because a qubit can represent a wide spectrum of values (massively parallel), whereas a bit can only be 1 or 0. Quantum hardware is very unlikely indeed to be used for the same kinds of applications as conventional. These are (future) computers for doing entirely different things -- eg molecular modelling (to help improve medicine and materials science). Physical matter is quantum, so it is impossible to model materials at the molecular level using any existing or potential digital computer. Rather, to truly model a quantum system, you need another quantum system -- hence a quantum computer.

[@Verlamian]

Though slightly better it seems you didn't fully absorb the comments - mine and those of the QC/QIT guy that you pinned - on your last quantum related video. As I said in a comment there, Scott Aaronson has described the idea that a qubit can *have* a value of 1 or 0 simultaneously as "the fundamental misstep of quantum computing popularization". More generally, superpositions don't mean what popular science writers - including far too many physicists and others who should know better - often say they mean (particles can't *be* in two or more places at once either). I also pointed out there why, since QT is a generalization of classical probability theory and the *appropriate* comparison is between a qubit and a classical *probabilistic* bit, it's equally misleading to say things like "a qubit can represent a far larger range of data values than a classical bit".

[@andreranulfo-dev8607]

As usual. Here I am to watch the Quantum Annual Update.

[@ExplainingComputers]

Thanks for watching. :)

[@pavan13]

Great video 👍 There's so many references in video description

[@ExplainingComputers]

There are indeed! :)

[@ObsidianMercian]

Thank you Chris, another brilliant update!

[@mikiethebikie]

Thanks so much Chris, this is a great service you provide. This bleeding edge stuff makes my head hurt.👍😁

I suppose this is a rather noobish question, but: Is theoretically possible to build user software like operating systems, device drivers, applications, videogames, computer-human interfaces exclusively on quantum processors? Can quantum processing ever entirely replace binary processing, or is it going to be more of an "extension" to it, like MMX and the like? I'm under the impression that quantum computers are more for calculating extremely complex math than for something like controlling hardware and user interfaces. I can't figure this out myself and it seems like I can't find anyone laying this out for me.

[@ExplainingComputers]

I think it is very unlikely indeed that user software/etc as you list will be run entire on quantum systems. There will always be a need for conventional hardware to handle I/O and to control and program the quantum processor, with a QPU being a co-processor as you describe. This is why IBM now talk about future "quantum-centric supercomputers" as discussed in this video. :)

[@radornkeldam]

@@ExplainingComputers Thanks for the answer. And the video!

[@SP-ny1fk]

Now we can rest assured that the computers running and defining our routines from the background of our lives will be ever-more efficient and inscrutable.

[@SmithnWesson]

IONQ is also a startup and they are doing great things and they actually have more funding than d-wave.

[@DanielWolf555]

Thanks for this interesting video! Have you heard of QODA? It is from Nvidia and similar to CUDA, just for quantum computers. Maybe a video about CUDA/QODA would be interesting.

[@johnm2012]

The trouble with CUDA is that it's proprietary. If there's to be a video about parallel computing on graphics hardware, I feel something more general would be more appropriate, like OpenCL, or GPUFORT if you prefer CUDA.

[@walts555]

👍 Good update. My faith in QC has also been strained by the increasing qubit overhead estimates for useful error correction. However, the proposition that four major tech companies are all simultaneously wrong seems unlikely--desperate logic perhaps, but I'll take it for now.

[@johnSmith-nb6qu]

this guy is literally your computer teacher from the 1989s same haircut everything.

[@nonsuch9301]

My understanding of superposition is not that the value of the qubit is both 1 and 0 at the same time. It can only be one or the other but the construct you are trying to apply to the qubit has to be valid despite not being able to tell if it is either 1 or 0. Only in that sense is it 'both' 1 or 0 . I'm not an expert or anything so if someone can clarify that would be great.

[@ExplainingComputers]

"Superposition" -- by definition -- refers to something (the qubit) having more than one state at the same time. That's what a superposition is. :)

[@Verlamian]

Your understanding is correct. I've already clarified this point in a comment below (and in comments on a previous video). Clearly, despite the conceptual simplicity, it's not getting through (again).

[@androth1502]

success or flop, research and dev. into quantum computing will give us new technologies.

[@rorytruman]

It is the implementation that I wonder about. For me even the most processor intensive tasks I would need to perform can be achieved by traditional silicon. I think the most exciting (and scarey) possibility would be to mimic organic neural systems where electrical 'binary' signals between nerve endings are 'coloured' with a chemical soup allowing different flavours of 0s and 1s. Quantum seems to support this kind of implementation. Or as we are beginning to see now devices are bigger than they need to be to accommodate connectivity like an SBC needs a big enough form factor to fit all those ports.

[@Remigrator]

You are my favorite Quantum robot 😁

[@ExplainingComputers]

Thanks. :)

[@handmade_videos]

Hallo, I agree with your elaborated opinion about the future of quantum computing. Very good and well made video! Thank you
