@ninahasacomputer 9 месяцев назад

There are papers showing promising results of some ML approaches to quantum computing, but do remember that they are only as good as the quantum algorithms being used, and the fidelity of the output. The vast majority of research ebing doing here is still theoretical, and uses quantum simulation, so it's a long way off true utility. There's also the issue the the QC industry itself can't agree whether anything useful will exist in the NISQ era we are in, or if we must try for perfect qubits. This is the core issue in QC. And it's an industry I work in so all of this pains me that we might never truly find proper utility (which to be clear doesnt exist yet).

@John_Mack 10 месяцев назад

I see the future of Quantum Computing to not be at the desktop scale, but instead going backward (in a good way) to the mini-computer scale with multiple desktops networked to a single large format computer and storage. These "quantum terminals" of course could be located anywhere as they can be wireless. The terminals in fact could be tablet and phone based. A Quantum Computer holds the promise of large-scale multi-layer and multi-task computing with less heat and better data management. I am blessed that I have had the opportunity to have worked on computers since the 70's from main-frame to mini to desktop and what appears to be a return to mini-scale computing. It's a shame that I have retired and will not get a chance to integrate this type of computing into a future workflow. Quantum Computers would be incredible at data management for the "Digital Twin" future in Architecture and Engineering.

@Mark-rw3kw 8 месяцев назад

The reason why error correction is needed, is that quantum mechanics (and computing) only deals with probabilities, not absolute facts. That is why the author of this video clearly stated it will never replace conventional computing, and can only be used where probabilities are acceptable, such as simulations, the same thing that super-computers are used for today. Super-computers (or quantum computers) will not solve inflation, war, federal deficits, or any of the major problems facing us today.

@tonysheerness2427 10 месяцев назад

How do they know quantum computers make errors? Do they run the same programme say 200 times to see if always gives the same answer?

@ExplainingComputers 10 месяцев назад

As far as I understand it, errors may be detected as you signal from inconsistent results. Or they may be detected via the creation of a logical qubit that combines the results of lots of physical qubits, so making it clear which physical qubit(s) has an error (ie you could compare the output of both the logical qubit and all the individual ones). Or errors may result in catastrophic failure -- so the algorythm (program) crashes and reports no output, or meaningless output.

A way to get to learn about low level coding for quantum computing and making it more accessible to ordinary people.

Thx Chris, they are supposed to do quantum jumps forward, but instead the speed of progress is mind blowing. I like the Darpa approach (not the Darpa itself) to fund a broad range of concepts which put a different spin on quantum computing (ok thats a lame joke with the spin). With such a lot of quantum experiments our understanding of quantum mechanic and dynamic will get a huge boost too.

@Mark-rw3kw 8 месяцев назад

No. Quantum Computing has nothing to do with "quantum jumps forward." It has to do with quantum mechanics and superposition where something can be in multiple states or places at the same time. So information in a quantum computer is not binary, either a 0 or 1, but can be many states in-between. Therefore, quantum computing is error prone and deals with probabilities, rather than absolute facts, which is why it can only be used for certain scientific simulations, etc, and not for conventional computing.

Hi Chris. What a great video. I'm forever astounded when people use the idea that the new Quantum Computers will just replace their desktop. As if the expense of one just to run Word, Excel and Outlook was worth it. In order to make the new PCs affordable, it's obvious the supercooled will have to be overcome and I fancy some of the big magnets and lasers options will need a lot of work to overcome the inherent noise issues with these systems. I agree with you that people's expectations on deliverability of homec sustems need to be managed. I remember the earlybPCs in the late 70s and look at how far we've come in thos 45 years or so. Personally, I'd like to see a a Cray sized super-quantum computer, coupled with AI, working on a research project looking at known knowledge, cross referencing topucs in new ways, and hopefully giving new insights into science, medicine, etc. Interesting times. Keep up the great work

@Mark-rw3kw 8 месяцев назад

Aside from the fact that QC's like from IBM need to operate at just above absolute zero temperature (-459 F), the reason why QC will not replace conventional computers is that QC's deal with probabilities, not facts, so they "might" be able to be used for scientific simulations that super-computers are used for today, but not for conventional computing that require 100% accuracy.

@yanntal954 10 месяцев назад

2:19 There's something that needs to be said here. No these companies aren't lying but at the same time they also didn't (yet) prove quantum computing is possible! The problem is with scaling, it could very well be that as you increase the computational capabilities of your quantum computer, its decoherence time shrinks FASTER than the computational power increase. You can imagine that yes, although it is stronger with more qubits that function properly, it's overall coherence time is so small that it just doesn't have enough time to do anything more than a "weaker" quantum computer with perhaps fewer qubits. So it could be that we can only have very weak quantum computers that don't really give us any advantage. It needs to be shown that the decoherence time shrinks slowly enough so that we reach the threshold with information that's still salvagble enough where error correcting codes are applicable and can deal with decoherence from there. My take is that, just like with any other model that can solve problems outside of complexity class P (DNA computing, Lasers in a maze that can solve the Hamiltonian path problem, etc) something just has to go exponential on you (DNA needs exponentially many molecules, and lasers needing exponentially large amounts of energy) and here it could be the coherence time shrinking exponentially.

I really like your videos about quantum computing . I have always felt it was a fraud, and have been hopefully waiting for somebody to explain it in a way that I can understand that it is not a fraud. So far that day has not arrived, but I watch your quantum computing videos each year, hoping that you can show that it is not a fraud. So far it’s still seems like a fraud. I will tune in next year for your update.

Quantum computers are clearly not a fraud since working systems exist. More like highly experimental and vastly different from the computers we use today. I would say that quantum computers of today are the equivalent of the ENIAC computer of the 20th century.

IN THE NOT TOO DISTANT FUTURE, NEXT SUNDAY A.D..... Me after installing and playing Crysis on a quantum computer: Hooray! It runs perfectly and smoothly! Bad joke for which I apologize for aside, this was another great quantum computing update video. ❤️

I still feel that the current state lf quantum computing is closer to the state of Nuclear Fusion power plants in the 80's than those of computers in the same era. In need of tremendous breakthrough, more than technological refinement.
