摘      要：正 Quantum teleportation of optical coherent states was demonstrated experimentally using squeezed-state entanglement. The quantum nature of the achieved teieportation was verified by the experimentally determined fidelity = 0.58±0.02, which describes the match between input end output states. A fidelity greater than 0.5 is not possible for coherent states without the use of entanglement This is the first realization of unconditional quantum telePortation where every state entering the device is actually teleported.
