  "abstract": "FINDING: Matthew Fisher proposes nuclear spin qubits (phosphorus-31) in Posner molecules as the physical substrate for quantum cognition, with decoherence timescale ~10⁵ s and a specific six-spin cluster geometry. | MATH: Fisher's model requires \\( ^{31}\\text{P} \\) nuclear spin \\( I = 1/2 \\), gyromagnetic ratio \\( \\gamma/2\\pi \\approx 17.235 \\, \\text{MHz/T} \\); Posner molecule \\( \\text{Ca}_9(\\text{PO}_4)_6 \\) contains 6 phosphate groups → 6 coupled spins; decoherence time \\( T_2 \\sim 10^5 \\, \\text{s} \\) at physiological temperature via spin-freezing (Zeno-like effect); quantum error threshold satisfied if \\( T_2 / T_{\\text{gate}} > 10^4 \\). Key symmetry: Posner cluster has \\( S_6 \\) (or \\( C_3 \\)) rotational symmetry — a 60° rotation axis, linking to hexagonal/crystallographic order. | CONNECTION: The \\( S_6 \\) point group (proper 6-fold rotation) is a crystallographic symmetry — directly related to the hexagonal lattice (root system \\( A_2 \\), base-60 division of circle).
