Nvidia CEO: Quantum Computers Won't Be Very Useful for Another 20 Years (pcmag.com) 23
Nvidia CEO Jensen Huang said quantum computers won't be very useful for another 20 years, causing stocks in this emerging sector to plunge more than 40% for a total market value loss of over $8 billion. "If you kind of said 15 years for very useful quantum computers, that'd probably be on the early side. If you said 30, is probably on the late side. But if you picked 20, I think a whole bunch of us would believe it," Huang said during a Q&A with analysts. PCMag reports: The field of quantum computing hasn't gotten nearly as much hype as generative AI and the tech giants promoting it in the past few years. Right now, part of the reason quantum computers aren't currently that helpful is because of their error rates. Nord Quantique CEO Julien Lemyre previously told PCMag that quantum error correction is the future of the field, and his firm is working on a solution. The errors that qubits, the basic unit of information in a quantum machine, currently make result in quantum computers being largely unhelpful. It's an essential hurdle to overcomeâ"but we don't currently know if or when quantum errors will be eliminated.
Chris Erven, CEO and co-founder of Kets Quantum, believes quantum computers will eventually pose a significant threat to cybersecurity. "China is making some of the largest investments in quantum computing, pumping in billions of dollars into research and development in the hope of being the first to create a large-scale, cryptographically relevant machine," Erven tells PCMag in a statement. "Although they may be a few years away from being fully operational, we know a quantum computer will be capable of breaking all traditional cyber defenses we currently use. So they, and others, are actively harvesting now, to decrypt later." "The 15 to 20-year timeline seems very realistic," said Ivana Delevska, investment chief of Spear Invest, which holds Rigetti and IonQ shares in an actively managed ETF. "That is roughly what it took Nvidia to develop accelerated computing."

That hasn't slowed AI hype so far.
Quantum computing was the scam, er, marketing hype from a couple of years ago. Now it's AI. Next year, will be something else.
It's hard work coming up with new scams every year or two, but the marks aren't a gullible as we want them to be! They keep catching on!

If you are doing quantum key distribution you are exploiting the fact that quantum phenomena are exceptionally delicate to set up optical channels that cannot be tapped or MiTMed without perturbing them.

Guess what? For the use cases where AI isn't good enough (like AGI, autonomous vehicles and robots), it's not used to generate revenue. For the use cases where AI is already good enough (image recognition, NLP, language translation, medical diagnostics, graphic design, etc.), it has been and will continue to generate a lot of revenue. Go figure.

Quantum computers wish they had the error rates of AI. They'd be amazing if you could reduce the error rate to even 99% wrong 1% right, for something simple like factoring a large prime. Each of your qbits literally collapses if you look at it funny, and you need to smack thousands of them around a bunch of logic gates while keeping them quantum.

If you limit your definition of "computer" to something with a traditional Von Neumann architecture (with a CPU, RAM, etc), then they certainly aren't that. But the history of computing includes a large number of other architectures as well (mechanical computers, water clocks, even people with notebooks and instructions) and as long as they are able to compute a result, they are, in the broader sense, computers.

Self serving nvidia spin as usual. Of course nvidia is invested up to the eyeballs in classical computing and are not prepared to service the upcoming quantum universe. So this is all about making noise to distract geeks like you and me from the interesting questions. Um, what's that called again? Oh yeah! FUD.
Bunch of fucking nvidia FUD, nothing more. If you want to know what impact quantum computing is going to have on you and your data center, do not listen to Jensen, whose only interest is preserving nvidias defacto monopoly over their shitty GPUs and garden variety tensor processors.
