"Such a mind would behave in a deterministic way based upon the laws of matter."
That's all well and good, but what exactly is meant by "deterministic", here? Any plausible interpretation of Quantum Mechanics will, at least at some point, accept that some results cannot be predicted except in a probabilistic sense; I can tell you that half of a few trillion or so deuterium atoms will decay after about six years, but I couldn't tell you which half.
I'm hesitant to go too far down the road of "quantum consciousness" -- in particular, I'm certainly not proposing that the origins of consciousness have already been "solved" since the discovery of QM -- but I'd suggest that nevertheless the laws of physics are rather less depressingly deterministic than the authors of your excerpt make out.
If I had to summarise my position best then it would probably be along the lines of: "I don't think that the dualist interpretation of mind and matter is the best starting point," -- which, to be clear, is not the same as saying that it's wrong. It is, however, clearly easier in principle to rule out a strictly material origin for consciousness, because you could actually try to test it. We aren't yet at that point, so far as I know -- but I think we're a lot closer now than ever before.
I guess another way of putting it might be that "at least reductionism can be more meaningfully ruled out".
