Nvidia's Huang Says 'Very Useful' Quantum Computers Likely Decades Away (yahoo.com)

(Wednesday January 08, 2025 @11:41AM (msmash) from the reality-check dept.)


Nvidia founder and chief executive Jensen Huang believes "very useful" quantum computers are [1]likely decades away , tempering expectations for the emerging technology. "If you kind of said 15 years for very useful quantum computers, that would probably be on the early side. If you said 30, it's probably on the late side," Huang said during Nvidia's analyst day. "If you picked 20, I think a whole bunch of us would believe it."

Or they're not. It depends on when we measure their existence.

With the glacial scaling we have observed the last 40 years or so, we may eventually get QCs that can do useful things, but > 100 years is a more realistic estimate. We may also never get them, conventional computers may stay ahead (the claims of "quantum supremacy" are just lies), or we may get them as demos, but far too expensive per computation to ever be used.

Think any proposed specific timeline is impossible to support or dismiss. The nature of this is that it will be advanced not by any currently known means, but by breakthroughs. The requisite breakthroughs might happen within 10 years, might never happen, might be fundamentally impossible.

Guy who makes "AI" chips disses quantum competitors in front of stock analysts. His stock price immediately shoots, quantum computer stocks dive.

Doesn't take a CUDA core to figure out this one.

My tech is red hot, your tech is doodley-squat. Indeed quantum computing gets real, his stock will nosedive with velocity never before seen.

At the point where some QC publically demonstrates quantum supremacy, it will be used almost regardless of cost. For certain organizations, the word "budget" doesn't really exist in the dictionary.

This reminds me of a series of talks Google hosted on fusion power. They had at least two experts in the field give presentations on the state of fusion for energy, one of which was Dr. Robert Bussard. Dr. Bussard died in 2007, and this presentation he did was shortly before his death, so it must be something like 20 years ago now.

One "complaint" (for lack of a better term) Dr. Bussard had in his presentation was funding for his research. He had some limited funds from the US Navy as the Navy had interes
