If conclusive evidence were found that human consciousness is fundamentally dependent on QM processes to function, that would be a Nobel Prize-worthy discovery. Aside from some minor papers exploring the topic, no such evidence has been found AFAIK.
In any event, positing some sort of "QM consciousness" does nothing to save the concept of free will. Where is the "free will" in a fundamentally random phenomenon? Whether one accepts determinism or not, the notion of free will is incoherent.So? Transistors used in modern computers directly depend on quantum effects (semiconductor physics was an outgrowth of QM) as well, yet we do not need to take into account QM when writing software or designing microprocessors.
