No, it does not. Actual science at this time says "we have no clue how this works". There is zero evidence either way and that makes the question open. Or have you forgotten that actual intelligence gets observed nowhere else? That alone makes a default to the physicalist explanation exceptionally non-scientific. Or maybe you think consciousness and intelligence are emergent properties of complexity? If so, that would be "magic" right there, because the whole cannot be more than the sum of its parts in physics.
The actual scientific fact at this time is that the question is completely open.
Incidentally, you are wrong about "quantum". The human brain is awash with quantum-effects. They happen all the time in the synapses, and there are about 1,000 trillion of those in a human brain backed very densely. Nobody knows what even tiny deviation in the probability distributions could do.
