But what happens inside a quantum computer is a coherent superposition. And it isn’t a coherent superposition of classical states, because there is no fact of the matter about the basis of a superposed state.
And yet each consciousness will still only see a classical state, or otherwise it would not answer exactly the same as the original consciousness. Hence this is an example of Many Worlds (even though it doesn’t rely on decoherence to work).
You’re starting at the end.
There’s no fact of the matter about how many consciousnesses there are, including whether there are any. The output of the whole system can be explained by computation. It might be “as if” a bunch of classical computations were occurring , but that doesn’t mean they are. A Giant Look Up Table can behave as though it is computing, but isnt.
Talking about the fact that each consciouness will only see a classical state doesn’t make sense, because they are in a quantum superposition state. Just like it does not make sense to say that the photon went either right or left in the double slit experiment.
