Quantum computers can emulate any classical computation. If a brain emulated on a quantum computer answers "no" when asked the question "are you conscious?" while the same brain emulated on a Pentium III processor answers "yes" when asked the same question, then you have a violation of the Church-Turing thesis.
The Church-Turing thesis doesn't show that a computer must be ignorant of everything about it. Have you not noticed that you can get both "yes" and "no" by polling human philosophers. What do you conclude from that?
This is a program that can determine something about its underlying hardware (whether its a classical or quantum computer). If instead, you hold that both emulations answer "yes", then you have a violation of the anti-zombie principle <https://www.lesswrong.com/posts/kYAuNJX2ecH2uFqZ9/the-generalized-anti-zombie-principle>. Either consequence is distasteful to me.If the quantum computer didn't decohere to a quasi-classcial mixture it would answer "Yes and no." (to every question).I am assuming in this example that the brain emulation is deterministic (no superpositions need be used as inputs).
I don't understand the relevance of that remark. Any pure input can be expressed as a superposition.
