Nuclear Spin Qubits in Phosphorus Complexes as Substrate for Quantum Cognition — E8 Intelligence Research
- 1Independent Researcher, United Kingdom
Abstract
FINDING: Matthew Fisher proposes nuclear spin qubits in phosphorus atoms (¹³C-³¹P molecular complexes) as the physical substrate for quantum cognition, with specific decoherence timescales and molecular geometries enabling neural-scale quantum processing. | MATH: Fisher's model requires spin coherence times T2 ≳ 10−3 s at physiological temperatures (~310 K); the key interaction is the hyperfine coupling A ≈ 100 MHz between ³¹P and ¹³C nuclear spins; the proposed molecular scaffold is a Posner molecule Ca9(PO4)6 — the phosphate cluster has 6 phosphorus atoms, each with spin-1/2 ³¹P, yielding a Hilbert space dimension 26 = 64 per Posner molecule; quantum entanglement between phosphorus spins is mediated via the J-coupling J ≈ 10–100 Hz between adjacent ³¹P nuclei through the calcium-oxygen lattice. | CONNECTION: The Posner molecule Ca9(PO4)6 exhibits approximate octahedral symmetry (p
