Quantum Models of Consciousness from a Quantum Information Science Perspective.

Summary

This perspective article categorizes quantum models of consciousness into three groups based on the brain level at which quantum mechanics might operate: electron delocalization within microtubules, the brain's electromagnetic field, or neurotransmitter-mediated interactions between neurons. The authors focus on the Posner model of cognition, presenting preliminary calculations on how entanglement of phosphate molecules is preserved within the geometric structure of Posner clusters. The work suggests that quantum information theory can improve understanding of brain functions.

Abstract

This perspective explores various quantum models of consciousness from the viewpoint of quantum information science, offering potential ideas and insights. The models under consideration can be categorized into three distinct groups based on the level at which quantum mechanics might operate within the brain: those suggesting that consciousness arises from electron delocalization within microtubules inside neurons, those proposing it emerges from the electromagnetic field surrounding the entire neural network, and those positing it originates from the interactions between individual neurons governed by neurotransmitter molecules. Our focus is particularly on the Posner model of cognition, for which we provide preliminary calculations on the preservation of entanglement of phosphate molecules within the geometric structure of Posner clusters. These findings provide valuable insights into how quantum information theory can enhance our understanding of brain functions.
