I agree classical computation is what is behind consciousness, so if quantum computation is the superposition of many classical computations, and if these classical computations instantiate minds, then the emulation of a mind on a quantum computer gives you many different conscious states existing at once. Our own classical world, is based on the quantum, so really, we don't even need to run a brain simulation in a quantum computer (that is already what is happening to us today, right now). > So it depends on whether the computations are sufficient to instantiate > such a world. > > > > >> >> That we can only access N-bits of a mind from any one world is >> irrelevant, as all the conscious states exist in the intermediate states, >> >> >> That's your story and you're sticking to it. >> > > > Do you disagree? > > > It is certainly relevant that we can only access N-bits of an N-qubit > computer.
