Oxford's 2025 High-Fidelity Quantum Teleportation via Entanglement Swapping and Bell States — E8 Intelligence Research

FINDING: Quantum teleportation relies on entanglement swapping and Bell state measurements, not physical matter transport; Oxford's 2025 breakthrough demonstrates high-fidelity teleportation across a quantum network node. | MATH: Bell state basis: \(|Φ^+ = {1}{√2}(|00 + |11)\), \(|Φ^- = {1}{√2}(|00 - |11)\), \(|Ψ^+ = {1}{√2}(|01 + |10)\), \(|Ψ^- = {1}{√2}(|01 - |10)\). Teleportation fidelity \(F = ψ | ρₒᵤₜ | ψ \) with \(F > 2/3\) for non-classical threshold. No new fundamental constants or ratios emerge from these videos. | CONNECTION: No direct geometric harmony ratios (0.382, 0.618, 0.786, 1.618, 2.618) or base-60 or crystallographic symmetries appear. The Bell states exhibit \(SU(2)\) symmetry, which is isomorphic to the double cover of \(SO(3)\), a rotation group linked to spherical harmonics but not to the spe Author: Andrew Stewart Caldin, Independent Researcher, UK.
