Quantum Coherence in Microtubules: Simulation Insights, Experimental Evidence Still Lacking — E8 Intelligence Research

FINDING: Microtubule quantum coherence evidence is emerging from simulations and cavity-QED analogs, but no quantitative experimental result confirming brain-level quantum effects is presented in these sources. | MATH: No new equations or constants extracted; references to "quantum beats" and "ground-state superposition" in cavity QED (arXiv:1401.3218) imply second-order correlation functions \( g⁽²⁾(τ) \) and Rabi frequencies, but no numerical values given. | CONNECTION: Microtubule lattice geometry is a helical/cylindrical structure with 13 protofilaments (a prime number) and 8 nm tubulin dimer spacing — a crystallographic-like lattice (p2 symmetry in projection), but no explicit golden-ratio or base-60 link in the provided material. | DEPTH: 3 — The sources are popular-science videos and one abstract; the mathematical content is thin, and no reproducible constants or ratios are supplied. The cavity-QED paper is rigorous but unrelated to biology. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
