That technology is likely quite a ways away from practical application, though. I think the prototype that was done at UC Berkley (I want to say it was) back in 2012 or 2013 was only able to find the prime factors of 15 half of the time. (The half of the time part is actually consistent, since that includes results of 1 and 15.)
The more recent test was a 52 qubit computer that did in 200 seconds what would take a standard computer 10000 years. But, like you said, it's really only beneficial for a certain subset of problems.
