Well, as a quantum computer can be simulated by a classical one (a
quantum computer can't compute what a classical computer can't)... it
will just be order of magnitude slower for the classical computer. So
I don't understand the 'perhaps by quantum one'.

I don't understand this either, if reality is computable, obviously
our consciousness is too.
