Yeah, yeah, whatever.  Nobody even knows whether quantum computing is possible.  Google, NASA, Lockheed Martin, and Los Alamos National Laboratory have all invested millions of dollars already into quantum computing.  D-Wave already has a working machine thanks to millions of dollars of investment except that it doesn't behave properly.  They can get it to work as a standard computer but cannot unlock its quantum computing abilities.
 
I don't think Microsoft will somehow magically figure out the physics problem.  "Doubling down" on nothing still provides the result of nothing.
 
Watch this:  a real good basic insight on the issue.

It seems like the problem is that it is hard to direct a computer to work in a useful fashion (the way you want it to work in order to solve some problem) without forcing the quantum particles to behave in a standard binary way.  In effect, our world is surrounded by quantum computing everywhere we look and touch; but we can not use nature to run our computer program any more than we can get D-Wave to run our quantum computer program.  At least that is the current status of the industry.
