quantum properties of brains that cannot be simulated by a conventional computer.

To the best of our knowledge, any "quantum property" can be simulated by a classical computer with approx. exponential slowdown. Obviously, a classical computer is not going to instantiate these quantum properties.

Is that obvious?

It should be. We can definitely build classical computers where quantum effects are negligible.

(For all we know, the individual transistors of these computers might have some subjective experience; but the computer as a whole won't.)

If the Church-Turing-Deutsch thesis is true and some kind of Digital Physics is an accurate depiction of reality then a simulation of physics should be indistinguishable from 'actual' physics. Saying subjective experience would not exist in the simulation under such circumstances would be a particularly bizarre form of dualism.

Saying subjective experience would not exist in the simulation under such circumstances would be a particularly bizarre form of dualism.

The same formal structure will exist, but it will be wholly unrelated to what we mean by "subjective experience". What's dualistic about this claim?
