Nice paper. Also manages to show a real problem that is a low-hanging 
fruit if we get quantum computers.

I never said that they were useless (if they work), just that the 
problem class they solve is a more specific one than what we solve 
(slowly) using our current computers.

Most computations done today are likely sorting, matrix operations and 
searching. But the ones we care most about tend to be simulations, and 
this is where quantum computers could shine.
