She's got a decidedly unscientific certainty to the statements she makes. Her opinions are just that and delivering her opinions as obvious facts is deceptive. Quantum computing has enormous potential. It may be expensive and may always be expensive and it may be noisy and this may never change but even with those problems it has enormous potential. If it's at all useful it can do things that seem like total magic right now. This power is known and this knowledge is what causes the seekers to pour so much time, effort, and money in. And Sabine is doing something very sneaky here. She makes a video that contains inflammatory rhetoric about a topic she knows little about and finishes it off by turning into a saleswomen hawking a predatory product that promises it can teach you how to think. And she gets paid for it. Unknown to most, the reason this video exists is to get Sabine paid. The only reason. This is why it is inflammatory. So you'll watch it. It's not inflammatory so it's closer to the truth. The topic isn't chosen because Sabine has strong feelings about it. It's pandering. It's clickbait. Advertising and even payment consistently and inevitably causes the reduction of speech into drama and propaganda. Each RU-vidr that engages in sponsorships falls into this trap and all their channels become hollow shells of their former glory. Honesty gets turned into drama. The depths are made shallow. The complex is made simple. The heartfelt is made insincere. The RU-vidr clearly only shows up because it's their job. The passion fades and becomes jadedness. Lies creep in. Exaggeration bulldozes over subtlety. Truth dwindles. And the fanboys keep cheering. Like lemmings. Their brains rotted. Their faculties stunted. Off the cliff they go. I dare call out the BS for what it is. I despise Sabine for her fakeness. Another video only made so that there's a place to tack an ad onto.

This reminds me of cloud computing. I was a recent hire at a software company and inherited a project a recently leaving partner signed on. It seems he sold it to the clients by peppering the document with the word cloud with little to no actual meaning reflectig what the technology did. Instead, it appeared to be the cure all for every problem they had or could have. In the 5 page document specifying what our company would do, he had signed us up for a job that would have taken a team of experts years to do and me, a lowly junior, ended up as the lead developer with only three months left in the contract. Suffice to say, it did not turn out well and the term cloud computing always leaves a bad taste in my mouth. Seems that snake oil salesmen are making the same use out of Quantum technologies.

@@rodrickard5528 not exactly. When cloud computing first came put, it became widely known as a term, but few people actually had any notion what it meant. This sort of dynamic breeds a certain group of people to use such a term as a cure-all of any problem. The snake oil salesmen basically. Back then, if you had a problem, just had to litter the term cloud into the conversation a few times and mamy would automatically think they new some great fix for almost any problem. It was the same hype crypto had and similar junk related to it. Cloud computing, when actually defined, I agree, wasn't anything great and just a play on how computers manage themselves. Still, back then it was more mystical that real.

I worked at Texas Instruments (TI) during the first Artificial Intelligence (AI) bubble, circa 1985-90 (my estimated dates). The issues described in Sabine's vid, were nearly identical to the marketplace hype and expectation of AI. TI developed and produced computer hardware that directly supported the Lisp programming language. To my knowledge, TI sold very few of these systems. Attractive commercial AI outcomes (algorithms, etc), took decades to develop, and used existing hardware.

I am so glad to hear someone else, someone with more credibility than I have, speak out about this. I've been dubious about quantum computing since the mid-90s. I'm not a physicist, but I've been doing software for many decades, and I've also worked with stochastic and probabilistic systems, and most of the time my understanding of the projections has veered off course as soon as the quantum jargon began to dominate the explanation. It always felt like hand-waving. I gave a talk at Interval where someone brought it up, and my reply (at the time) was "Yes, quantum computing will give you the right answer, and it will deliver it faster than conventional computing, but it will also deliver a multitude of wrong answers, so you'll have to go through them all to determine which one was correct." [edit] Even fuzzy computing does better than that. I just went back and noticed the cat on the cover of the Hoofnagle and Garfinkle book, but I couldn't tell if it was alive or dead.

As a computing specialist myself I couldn't disagree with her more. An operation that's used heavily in AI, matrix multiplication, can be done on quantum computers. If a quantum computer is sufficiently scaled up, and these operations were run to train an AI, the amount of training on that AI you could do within a short period of time is ridiculous. This becomes increasingly important as data sets are getting bigger and bigger. I've sat around for hours waiting for a smaller model to train on traditional top end silicon hardware, imagine the bigger models. Quantum computers will revolutionise AI, and that's just one example. Quantum computers aren't going away, they're going to get better and better, and a bitter old lady who's mad that their obscure research isn't getting as much money as quantum computing won't stop it. There's hype but there's also substance there. Of course, it won't ever live up to the hype, no new tech does, but eventually it will exceed it. It's really unscientific to discourage quantum computers by saying it's a dead end.

The problem is that quantum computers will almost certainly be useless for decades just due to physics. Until someone can discover a room temperature superconductor and a way to stop particles in superposition from decohering (I don't believe this even possible), most people won't even be able to have a supercomputer, let alone use it, and even if a way is found, we have maybe a few algorithms that are actually useful, and creating more would require even more work and even more research.

There is commercial hype and then there is scientific hype. Don't confuse the two of them. Commercial hype about possible technological breakthroughs tend to inflate and collapse very easily. In 1822 Charles Babbage, the father of the computer, came up with a design for a mechanical computer that he called the difference engine. The English government funded him to make his design a reality but the metalworking technology at the time was too primitive. After 20 years the government gave up and considered the investment a complete failure. It wasn't until the invention of electronic circuits in the 20th century that computers exploded and became a part of everyday life. The theoretical possibilities of computers in 1822 looked just as promising as the theoretical promises of quantum computers look today. We may currently not have the technological sophistication to make quantum computers commercially profitable, but this should not deter us from pursuing further research and development into this fascinating technology.

Also, from an algorithmic standpoint it doesn't matter if an individual algorithm is of use or not. All algorithms fall into certain categories of complexity and approaches to solving them. There are only a handful of distinct approaches that are modified and repurposed for many use cases. If you, for instance, could find a way to solve sudoku puzzles in polynomial time, it would only take a matter of a few years to have several approaches for solving protein folding in polynomial time published.

The issue is that quantum computers do not allow you to solve NP complete problems in polynomial time. The algorithms we know of so far only apply to a few specialty problems.

@@sccur Maybe. My point is that even if solving one problem often leads to many being solved in computer science it doesn't mean that any of the quantum algorithms are particularly useful even when considering this point.

Sabine, you are my favorite Physicist AND my favorite German. You speak in real and fairly understandable terms. Please continue to bring us these mini-summations of Physics - you might save a lot of middle class people from investments in companies that have little chance of ever making a profit. This is a valuable thing you do.

I always feel like the pursuit of quantum computing will teach us about edge cases related to quantum mechanics, some of which may provide fruit. After hearing your video, I feel like we should focus more on length of time staying coherent so we can at least play with the system. It's probably 20 years out along with fusion reactors and artificial general intelligence.

First of all, thank you for presenting this in such a clear and non-BS way! I’m currently working “around” post-quantum cryptography and quantum networking (from a technology strategy and standards point of view, not as a researcher) a, and also worked in artificial intelligence (as a researcher) in the 1980s and early 1990s. I see a strong parallel between the current quantum bubble and the AI bubble of 1985-1990 or so. AI and Machine Learning recovered after a dry spell of a few years, but this was mostly because of Moore’s Law and the explosion of the internet making things like big data and ultra-fast tiny devices practical. As you point out, these solutions don’t apply to quantum technology, despite the fact that people are expecting them to. I’m near the end of my career, and it’s kind of sad that we seem to have fallen down this rathole - I would have preferred to have finished on a high note.

The cooling system for the qubits is really interesting. I'll have to see if your other videos talk about it, but it uses liquid helium and then anonther stage of Helium 3 to make it below 4 kelvin.

About the only thing I'd nitpick is that I hate the simplification of "Qubits store things as superpositions". With all of the quack and woo going around, that's very misunderstood, and using that simplification only furthers the public misconception. I would much rather specify that "Each Qubit is mathematically equivalent to a simple pure sine wave. And quantum computing is simply adding up each waveform until a single constructive interference pattern is left behind, which should represent our answer".

Another bubble that will burst in the next few years will be FSD - Full Self Driving. The programmers working hard on vector spaces and all modes of computer learning are quickly learning that the human mind is much more diversified and complex than what they originally thought, and cannot be emulated with the current hardware and learning theories...

Don't listen to her, quantum computing will be one of the most important inventions this century. I hope you know how much it will revolutionise AI eventually: for example quantum systems can be used for matrix multiplication, an operation that's repeated millions/billions+ times to train an AI model. Imagine the complexity of an AI trained making use of this operation, it'd run rings around traditional hardware.

@@benj6964 no, and it will likely not have a real world use for matrix multiplication for a long, long, long time. Matrix multiplication is highly parallelizable, and GPUs are incredibly good at their computation. Even with a hypothetically faster quantum algorithm, the pure power we can commit to matrix multiplication will likely dwarf any computational efficiencies.
