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.

Btw: What a quantum computer can reliably do these days, is tell you 21 is 3 x 7. And it takes hours and quite some traditional computing to do that.

We've progressed a bit further than that. But for anyone interested in actual applications for quantum computers... They'll have to wait. It's research at this point. We're making progress one step at a time. But so far no one has even demostrated we're able to scale those computers to a useful size.
So I'd say we're somewhere close to the origin of the axes. Or on a different graph for research that's still science fiction. Together with nuclear fusion power plants, thorium cars, space ships and hypothetical battery chemistry that'll make our electric cars go 5000 miles and not degrade over time.
[Edit: The Wikipedia Article: Quantum comuting also has some good references.]
That's not entirely true. There are companies right now with prototypes solving real world problems.
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?
Not the one I was thinking about. Sandbox AQ is the one that came to mind.
