Quantum Teleportation: Entanglement-Based State Transfer, Not Sci-Fi Matter Transport — E8 Intelligence Research

FINDING: Quantum teleportation is a real, experimentally-verified protocol for transferring quantum states via entanglement, not a sci-fi matter transport; recent Oxford and Japanese advances push distance and fidelity. | MATH: Core protocol uses Bell states (maximally entangled qubit pairs): |Φ⁺⟩ = (|00⟩ + |11⟩)/√2, |Ψ⁺⟩ = (|01⟩ + |10⟩)/√2. Teleportation requires 2 classical bits + 1 shared ebit (entangled bit) per qubit. Fidelity F = |⟨ψ_target|ψ_received⟩|²; ideal F=1, current experiments report F > 0.9. No matter/energy is transmitted — only quantum information (state vector |ψ⟩ = α|0⟩ + β|1⟩, |α|²+|β|²=1). | CONNECTION: Bell states are 4 orthogonal vectors in ℂ²⊗ℂ² — a tetrahedral symmetry (A3 root system, 4 vertices, 6 edges). The √2 normalization is the same factor linking 45° rotation in 2D (cos45°=sin45°=1/√2 ≈ 0.707). The ratio 0.707² = 0.5 — the probability of each Bell outcome. No golden ratio appears in the standard protocol; however, the 2-bit classical overhead per 1 qub
