While quantum teleportation is fueled by a pair of maximally entangled resource qubits, it is vulnerable to decoherence. An international team of researchers (China, Finland) proposed an efficient quantum teleportation protocol in the presence of pure decoherence and without entangled resource qubits entering the Bell-state measurement. They used multipartite hybrid entanglement between the auxiliary qubits and their local environments within the open–quantum system context. With a hybrid-entangled initial state, it is the decoherence that allowed them to achieve high fidelities. They demonstrated their protocol in an all-optical experiment… read more.
