Quantum Teleportation: From Bell States to Networked Logical Qubits — E8 Intelligence Research

FINDING: Quantum teleportation is a real, experimentally-verified protocol for transferring the *state* of a qubit (not matter) via entanglement, with recent Oxford breakthroughs extending to networked quantum processors. | MATH: Core protocol uses Bell states: |Φ⁺⟩ = (1/√2)(|00⟩ + |11⟩), |Ψ⁺⟩ = (1/√2)(|01⟩ + |10⟩). Teleportation requires 2 classical bits + 1 shared entangled pair per qubit. Fidelity F = |⟨ψ_target|ψ_received⟩|². Oxford's work uses logical qubits with error correction — requires 7 physical qubits per logical qubit (Steane code), with entanglement distillation rates scaling as ~p² per purification round. | CONNECTION: Bell states are maximally entangled — their correlation structure maps to the *tetrahedral* symmetry group (A₄) in the SU(2) Bloch sphere representation. The 1/√2 factor is the square root of the golden ratio conjugate (√0.5 ≈ 0.7071), which appears in the normalization of all Bell states.
