Quantum cognition: The possibility of processing with nuclear spins in the brain

The quantum mind or quantum consciousness group of hypotheses propose that classical mechanics cannot explain consciousness. Quantum theory is used to insert models of cognition that target to be more innovative than models based on traditional classical probability theory, which includes cognitive modeling phenomena in science. At the moment we can say that there is no clearly defined neurophysiological mechanisms of creation of the quantum-like representation of information in the brain, but we can mention the hypothesis of matching the information processing in the brain with quantum information and probability with contextuality as the key word. Using limited cognitive resources, incompatibility provides humans the means for answering an unlimited number of questions, thus promoting parsimony and cognitive economy.

The Brain

Controversial hypotheses to explain consciousness exist in many fields of science, psychology and philosophy. Recent experimental findings in quantum cognition and magnetic resonance imaging have added new controversies to the field, suggesting that the mind may be based on quantum computing. Quantum computers process information in quantum bits (qubits) using quantum gates. At a first glance, it seems unrealistic or impossible that the brain can meet the challenges to provide either of these. Nevertheless, we show here why the brain has the incredible ability to perform quantum computing and how that may be realized.

Fundamental Requirement

It has been suggested that 31 P nuclear spins in Ca 9 (PO 4 ) 6 molecules could form the basis of a quantum mechanism for neural processing in the brain. A fundamental requirement of this proposal is that spins in different Ca 9 (PO 4 ) 6 molecules can become entangled and remain so for periods (estimated at many hours) that hugely exceed typical 31 P spin relaxation times. Here, we consider the coherent and incoherent spin dynamics of Ca 9 (PO 4 ) 6 arising from dipolar and scalar spin-spin interactions and derive an upper bound of 37 min on the entanglement lifetime under idealized physiological conditions. We argue that the spin relaxation in Ca 9 (PO 4 ) 6 is likely to be much faster than this estimate.
