Towards the end of my comments on a BBC news article titled "quantum physics explanation for smell", I started to have second thoughts about how "quantum" these results were ...
... If these results are replicated, then Turin gets a Nobel.
If noses use these 'quantum' effects, then it's pretty much certain that neurons do as well.
Does that mean our brains are 'quantum computers'? I need help from Aaronson. This 'quantization' sites on the micro-macro boundary. Not all quantized vibrations are quantum physics....
These look like *really* interesting experiments! And it's a priori plausible that smell would involve some quantum effect -- we already know that ... photosynthesis and bird navigation do.
If true, this doesn't IN ANY WAY imply that the brain is a "quantum computer" in the sense of using quantum coherence to speed up computation. That's a separate question, and any such suggestion would still need to overcome the problem of how entanglement could survive in the brain for any appreciable length of time.
 Born in 1981, when I left college. Sob.
 Incidentally, if I read Aaronson correctly, he suspects quantum computing is possible, but it won't solve radically new problems (and thus won't destroy the world economy if it works).
