Does these “companies” includes the one that were outed for just doing computation on plain old processors and claiming they had made huge breakthrough in quantum computing?
Comment on Regarding this picture, where do you think quantum computers lie and why?
feannag@sh.itjust.works 4 weeks agoThat’s not entirely true. There are companies right now with prototypes solving real world problems.

Not the one I was thinking about. Sandbox AQ is the one that came to mind.

If you have a concrete example I’d love to hear it

Sandbox AQ is one I’ve heard about. Pretty sure they are at least at the prototype stage.

That certainly counts as hype. But I wonder if there's any independent information out there about these computers. All I can find is self-advertising and news about investors. I mean we occasionally do get these claims that someone proved quantum supremacy. But as far as I know the validity often isn't clear or the results aren't reproduced yet. And sadly I can't skim the papers since lots of them aren't open access.
And for research it doesn't matter if you need days to cool down the computer just for one calculation. Or if most results are wrong due to noise and you have to re-do every computation on a traditional computer to check which results are correct. But I'd expect it takes them years or decades from a protopype like that to something actually useful. And as of now we haven't even solved superconductivity or the temperatures or decoherence. So I'm always a bit careful with these claims frome some quantum startups.

This is their only product on the market which has quantum in their product description. It apparently uses “quantum sensors” to provide location information. I don’t know how it works. I think they have made a hard shift in their strategy in the last 2 years by offering AI solutions instead.

Looks like they do! I’d only heard about them in passing, but here’s an article: www.mdpi.com/1424-8220/24/16/5402
