It's not axiomatic, I checked. Consciousness has the wrong kinds of properties to be physical. Physics is epistemically objective. Consciousness is epistemically subjective.
It's unlikely quantum effects play any realistic role in brain processes. If they do somehow play a role in awareness an AI could construct modules that utilize quantum effects in any case so this doesn't rule out conscious or aware AIs

All the components for a quantum amplifier exist in the brain. Indeed it would better explain why it maintains the blood-brain barrier. You're thinking of maintaining quantum coherence. That's not how it works.
-
The blood-brain exists to protect the brain from blood-born infections. Are you referring to Roger Penrose's theory about microtubes in the brain? It didn't have many supporters last time I checked
-
If it protects from infections better than letting white blood cells in, every major organ would have one. That's what they say it does because they don't know what it's actually for.
-
How could it act as a 'quantum amplifier' if it doesn't maintain quantum coherence at all?
-
Penrose's microtubules are supposed to maintain coherence. A quantum amplifier measures and amplifies decoherence events. And it is only a candidate machine - this is an empirical question. There's little point arguing rigorously about something that may not exist.
-
I think Penrose's theory is unlikely but it doesn't matter regarding the original question, because if that is how the brain becomes aware you could build an AI with quantum microtubes to make a conscious AI. I think any feature that can evolve can be artificially replicated
-
Of course. But not accidentally.
