According to Matthew Fisher, Professor of Physics at the University of California at Santa Barbara, the nuclear spin of phosphate atoms could serve as rudimentary quantum bits (so-called ‘qubits’) of information in the brain, since such phosphate atoms, bonded with calcium in Posner molecules (clusters of nine calcium atoms and six phosphorus atoms), can prevent coherent neural ‘qubits’ from collapsing into decoherence (non-quantum states) for long enough to enable the brain to function somewhat like a quantum computer.
