[obfuscate]

There's a huge difference between molecule-scale quantum chemical phenomena (as in photosynthesis) and quantum computation. Finding the former in the brain would be very cool, but it wouldn't be terribly surprising or revolutionize cognitive science the way the latter would.

It is thought that photosynthesis uses quantum computation to determine how to move energy internally within a cell. http://www.rsc.org/chemistryworld/Issues/2007/May/Photosynth...
