Attosecond Entanglement and Quantum Correlations Across 1200 km — E8 Intelligence Research

FINDING: Quantum entanglement confirmed over 1200 km (satellite-based) and entanglement formation timed at attosecond scales; MIT double-slit with single photons revalidates Bohr's complementarity; hybrid quantum circuits reveal universal statistical laws via random-matrix theory. MATH: - Entanglement distance: \(1.2 × 10^3\) km — no known speed limit violation, but formation time \(~ 10⁻¹⁸\) s (attosecond) implies an effective correlation rate \(~ 10²¹\) m/s if naively divided by distance — but this is **not** a signal speed; it's the timescale of local wavefunction collapse/entanglement generation. - Double-slit with single photons: interference pattern visibility \(V\) and which-path information \(D\) satisfy \(V^2 + D^2 ≤ 1\) (Englert–Greenberger–Yasin duality relation). - Hybrid quantum circuits: entanglement entropy \(S ~ c log L\) (critical) or \(S ~ aL\) (volume law) with random unitary ensembles; spectral statistics follow Wigner–Dyson (GUE/G Author: Andrew Stewart Caldin, Independent Researcher, UK.
