Re: Lets see it working then

So, if I had one of these devices in front of me now and I set it to solve a 1000-node travelling salesman problem, would it be able to spit the answer straight back

As I understand it, a perfect 1024-qubit quantum computer ought to be able to do that. (My own belief is that our attempts to build such a device will always fail, and will tell us something interesting about the nature of the universe once the reasons for failure are well-understood).

Clearly these devices are imperfect. I think there's some debate over whether they are actually quantum computers at all in any meaningful sense. But if they can outperform a conventional compute cluster eating a few megawatts and as much financial capital as it takes, I should think that's good enough for the time being.
