Three observations about your post:
1) The idea that quantum tunnelling plays an important role in brain function is interesting but speculative. If you look at the existing literature on neuroscience and the neural basis of learning, you'll see that 99.999% of it simply makes no reference to "quantum tunnelling".
2) There are many systems which can technically be called "non-deterministic", but for which non-deterministic part just isn't important. The opening of a sodium channel in a cardiac cell is ultimately non-deterministic and probabilistic (you certainly can't project the trajectory of every ion), but the errors tend to cancel out and just aren't important for predicting how the cell behaves. To paraphrase Isaac Asimov: We can't predict the behavior of individual atoms, but we know that if we have a closed container full of helium atoms and we double the temperature, the pressure will exactly double.
3) If we *did* make the discovery that "quantum tunnelling" (or other probabilistic, non-deterministic behavior) is somehow essential for brain function... and that's a VERY big if... there is no reason to think that this behavior couldn't be emulated by a machine.
