And you're never going to find a being that behaves

You need only a quantum computer with enough qubits.
Can you prove that? How does this quantum intelligence
ever arrive at a definite decision?
Prove? No. But I think I can justify it:
1. Quantum computers are Turing equivalent, they can compute
anything a classical computer can.
2. Human brains are believed to operate according to physical
laws, all known of which are computable.
3. Humans are conscious.
4. By any of: Chalmers's principle of "Organizational
invariance", or "multiple realizability", or the "Generalized
Anti-Zombie Principle", or the "computational theory of mind",
a functionally equivalent computation to that of a conscious
human brain will be equivalently conscious to that brain.
5. Quantum computers are reversible.
By 1 & 2, a quantum computer can simulate a human brain. By 3
& 4, such an emulation will be conscious. By 5 any computation
performed by a quantum computer can be quantum erased by
reversing the circuit back to its starting state.
It reaches a definite decision by virtue of completing its
processing before ultimately being reversed. This prevents an
outside observer from learning the decision, but it's made
nonetheless during the course of the processing.
How do you know that it has reached a definite decision? Without
having it print out some irreversible record? If it prints out a
(pseudo-)classical record, the initial state is not recoverable.

By either:
1. Analyzing the circuit
But the question is whether such a circuit is possible.
2. Having the circuit do something useful and verifiable (as in my
factoring example)
How would you know that had a causal connection to the quantum erasable
knowledge?
3. Having the circuit output that it did observe a definite value but
without reporting which value it observed (as in Deutsch's original
example)
Again, how do you know such a circuit is possible? Most quantum
computations only produce probable answers in a decohered readout.
