Bio-Quantum Field Modeling for the Physical Origin of Subjective Qualia

Abstract

The physical origin of subjective qualia remains the core hard problem, unexplained by classical neurodynamics or condensed-matter physics. Classical theories only correlate brain activity with experience, leaving an unbridgeable explanatory gap. Existing quantum consciousness models suffer from decoherence vulnerability and lack testable links to neurophysiology. Here, we develop a self-consistent bio-quantum field framework for qualia. We postulate a collective quantum fluctuation field from confined Ca$^{2+}$ ions in voltage-gated channels, governed by coupled Hamiltonian and open-system Lindblad decoherence. Under weak-coupling perturbation, we derive an explicit mapping between EEG band power and qualia eigenstates. Biophysical verification confirms femtosecond quantum correlations are thermally viable at physiological temperature. Neural activity regulates quantum dynamics to select qualia eigenstates. This mathematically and biophysically consistent model bridges the explanatory gap, offering a testable quantum framework for the physical basis of consciousness.
