That is unfortunate, because as far as I am concerned everyhting
I am saying is obvious. (Have you read "The fabric of Reality" ?)

A computer that exploits quantum superpositions to achieve parallelism.

A universe (or multiverse) in which quantum physics is a true
description of reality.

It exploits quantum physics.

Superpositions are an implication of quantum mechanics. Schrodinger's
Cat
was mooted decades before anyone even thought of quantum computaion.
