MERLIN SCIENCE — Quantum Teleportation Verified: Entanglement Fidelity, Not Classical B — E8 Intelligence Research

Today's finding is this: quantum teleportation is experimentally verified, and its scaling is governed strictly by entanglement fidelity, not by the classical bits used in the protocol. That is the clean sentence. The context is a field that has long been haunted by a seductive ambiguity—whether teleportation's limits come from classical communication or from the quality of the shared quantum resource. Oxford's recent work, moving teleportation between distant processors, and the Japanese solid-state results, both point to the same conclusion. The classical channel is necessary but it is not the bottleneck. The bottleneck is how well your entangled state survives distance and decoherence. Here is the mechanism, in terms you can check. For one qubit, the protocol uses a Bell state, two classical bits, and one ebit of shared entanglement. The fidelity of the output state is F, and the threshold for any non-classical advantage is F greater than two-thirds. If you teleport N qubits, the s Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
