Quantum Consciousness: Fragmented Metrics, Converging Theories — E8 Intelligence Research

FINDING: Consciousness research in 2025-2026 converges on quantum measurement (gravity-induced collapse) and quantum biology (superradiance), but no single quantitative metric of consciousness has emerged; the field remains definitionally fragmented. MATH: - **Gravity-induced collapse** (Fuentes, Penrose-Diosi type): collapse rate ≈ \( E_G / \hbar \) where \( E_G = \frac{1}{4\pi G}\int (\nabla \Phi)^2 d^3x \) — gravitational self-energy difference between superposed mass distributions. No new constant; relies on \( G, \hbar, c \). - **Superradiance** (Kurian): collective emission rate enhancement \( \Gamma_{\text{super}} = N \Gamma_{\text{spontaneous}} \) for \( N \) coherent emitters; criticality condition \( \Gamma_{\text{super}} \tau_{\text{decoherence}} \gg 1 \). Implies a threshold photon count \( N_c \sim (\Gamma_{\text{sp}} \tau_{\text{dec}})^{-1} \). - **Consciousness markers** (modern animal studies): no closed-form equation; uses behavioral/neural correlates (e.g., i Author: Andrew Stewart Caldin, Independent Researcher, UK.
