[ExI] D-Wave's Quantum Computer

[Joshua Job]

They are general purpose, in principle. But speed improvements will likely
only come from special problems, and their fragility and likely low average
clock speed will mean they will likely never be anything more than a
special purpose chip component, sort of like a GPU or arithmetic module.
