Can you be specific? Why does quantum computing depend on both
states of a qubit(?) be occupied simultaneously? Can the
system toggle between those states, yet not be in both
simultaneously? Couldn't quantum computing work, or say be
conceptualized with his model? TIA, AG
IOW, is the model of superposition you use in quantum computing a
necessary condition for its success, or could you use the
information-only model of the superposition and get the same
result. AG
In order to explain the final result of the computation appearing in
the measured qubits, each of the intermediate states must have existed
and interacted, all the while remaining in a super position
(completely isolated from the environment that contains the quantum
computer) for the duration of the computation. The computation might
have been a very long one, and may have involved vast numbers of
states simultaneously held by the qubits during the computation. Each
of these states is designed by the quantum computation to interfere in
such a way to that in most of the branches the measured qubits will
yield the same result.
We know we can prepare a quantum computation. We know we can measure
the qubits afterwards to get the final answer.
The big question of "what is going on in the middle?" can only be
answered by resorting to asking what the theory can tell us of what
the wave function is doing to perform and implement the computation
while we are not measuring it.
If one denies the existence of the wave function however, it leaves no
room for talking about these intermediate states that are necessary to
explain how the final result of the computation ends up in the qubits.
And all those qubits exist in the same world since they have to
interfere in order to amplify the probability of the result and suppress
others.
