Except the experts say quantum computers would only be good for certain
things.  Like searching mega databases or cracking keys.  Some
applications would not run well on a computer will more than two bits. 
I don't know how rendering would work here.  I read that a quantum
computer would search a database by looking at all of the entries at one
time.  So maybe one could render every pixel at once?!
