Quantum Teleportation Advances: 1,400 km Satellite and Multi-Qubit Demonstrations — E8 Intelligence Research

Abstract
FINDING: Quantum teleportation transfers quantum states (not matter) via entanglement, with recent demonstrations up to 1,400 km (satellite) and multi-qubit (3-qubit) teleportation by Kyoto/Hiroshima groups. | MATH: Core protocol (Bennett et al. 1993) uses a Bell-state measurement (4 outcomes) + 2 classical bits to teleport 1 qubit. State fidelity F = |⟨ψ_in|ψ_out⟩|²; for ideal teleportation F=1. Entanglement resource: Bell pair |Φ⁺⟩ = (|00⟩+|11⟩)/√2. Teleportation distance d = 1,400 km (Micius satellite, 2017); multi-qubit scaling: N qubits require N Bell pairs and 2N classical bits. No matter/energy transfer — only quantum information (Hilbert-space coefficients). | CONNECTION: The Bell basis is a 4-element orthonormal set in ℂ²⊗ℂ² — isomorphic to the tetrahedral group (A₄) and the root system of SU(4). The √2 normalization in Bell states echoes the 1/√2 = 0.7071 (not in your list, but note 0.7071² = 0.5 — the half-angle of 45°, related to 0.707/0.707 symmetry). The 4 Bell states cor
