Masers and lasers use Bose-condensate of photons in cavity, right? Also supercondictors use Bose-condensate (of Cuper pairs which are bosons as they consist of two paired electrons with opposite spin), liquid He (zero spin of atom = boson) - in all these condensates all bosons occupy the same quantum state - these and many other phenomena are experimentally known for long. As well as Fermi condensates - free electrons in condictors (all occupying different states), bonded electrons in atoms and shared electrons in molecules, bonded protons and neutrons in nuclei, etc.

Richard, question for you: how can someone STORE information in a quantum system in which ALL particles have the SAME quantum numbers, i.e. are in completely indistinguishable states (this is what is called Bose-Einstein condensate)? Such system can only store 1 bit of information. Is it enough for conscious state of brain - 1 bit?
