Attosecond Entanglement, Satellite Links, and Universal Quantum Circuit Statistics — E8 Intelligence Research

FINDING: Quantum entanglement formation measured at attosecond timescales; single-photon double-slit confirms Bohr's complementarity; entanglement maintained over 1200 km via satellite (Micius-class); hybrid quantum circuits show universal statistical behavior via random-matrix theory. MATH: - Attosecond scale: \(10⁻¹⁸\) s — entanglement formation time \(τ ~ /Ecoupling\) (if coupling energy ~ eV, \(τ ~ 10⁻¹⁵\)–\(10⁻¹⁸\) s, consistent). - 1200 km: entanglement fidelity decay \(∝ e^{-L/Lₐₜₜ}\) with \(Lₐₜₜ ≈ 22\) km (fiber) → satellite free-space \(Lₐₜₜ ~ 1000\)+ km (atmospheric windows). - Hybrid circuits: random-matrix universality → spectral statistics follow Wigner-Dyson (GOE/GUE) with level spacing ratio \(r ~ 0.5307\) (GOE) or \(0.6027\) (GUE) — not golden ratio, but close to \(0.618\) in GUE case (interesting but not exact). - Double-slit single-photon: interference visibility \(V = (I_{ Author: Andrew Stewart Caldin, Independent Researcher, UK.
