I don't believe quantum computers are intended to replace
conventional computers entirely, they're just much faster at
some specific tasks, so no.

It sounds like that's still some time away. As it's an Australian
invention, odds are that the Chinese will indeed end up building
the end product instead of us Aussies though (grumble).

I bet the NSA will be the first in any case. For that matter maybe
their own IARPA scientists already figured this out years ago and
their research was just kept secret.

"IARPA is a major funder of quantum computing research due to its
 applications in quantum cryptography. As of 2009, IARPA was said
 to provide a large portion of quantum computing funding resources
 in the United States."

At worst it might need an extra chip for increased speed.

You can't trust audio recordings of people anyway, just due to
editing.
