The brain is chaotic, as such small fluctuations in initial conditions will
rapidly lead to divergent results. So even if the two brains are initially
identical and in identical environments QM will lead to divergence over
time.

Note: I am not suggesting weird QM affects a la Hameroff and Penrose, but
more mundane affects of QM on the exact rate of chemical and
electrophysical reactions in the brain.
