Personally I find quantum computers really impressive, and they havent been given its righteous hype.

I know they won't be something everyone has in their house but it will greatly improve some services.

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 the quantum startups.

And does the company you mentioned actually own a quantum computer prototype? Because it seems their focus is writing algorithms/software.

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.

Edit: From their Youtube comment

The core system of AQNav is a suite of quantum sensors that reads the crustal magnetic field of the Earth, along with proprietary AI algorithms that work to de-noise that signal and provide real-time location information. That's a very different process, compared to inertial navigation systems
