Satellite-Scale and Sunlight-Based Quantum Entanglement with Universal Hybrid Circuit Dynamics — E8 Intelligence Research

FINDING: Quantum entanglement demonstrated at 1200 km (satellite-scale) and via ordinary sunlight without lasers; hybrid quantum circuits show universal statistical laws in entanglement dynamics. | MATH: Entanglement distance \(d = 1200\) km; sunlight entanglement implies photon-pair correlations without coherent laser phase — key parameter is the Schmidt rank \(K\) (effective number of entangled modes), which for thermal sunlight is \(K \gg 1\) (broadband, low purity). Hybrid circuit dynamics: entanglement entropy \(S(t)\) follows \(S(t) \sim s_{\text{eq}} \, t\) for \(t < t_{\text{th}}\), then saturates to volume-law \(S \sim \alpha L\) (system size \(L\)); the transition occurs at measurement rate \(p_c\) where \(p_c \approx 0.15\)–\(0.17\) for qubit chains (numerical, not exact). | CONNECTION: The 1200 km distance is not a golden ratio multiple, but the ratio of Earth's radius \(R_E \approx 6371\) km to 1200 km is \(6371/1200 \approx 5.309\) — no direct 0.618/1.618 link.
