利用压缩态纠缠实现了光相干态的量子隐形传态。通过实验确定的保真度F-exp = 0.58 +/- 0.02验证了所实现的隐形传态的量子性质，该保真度描述了输入和输出状态之间的匹配。如果不使用纠缠，相干态的保真度不可能大于0.5。这是第一次实现无条件量子隐形传态，其中每个进入设备的状态实际上都是隐形传态。
Quantum teleportation of optical coherent states was demonstrated experimentally using squeezed-state entanglement. The quantum nature of the achieved teleportation was verified by the experimentally determined fidelity F-exp = 0.58 +/- 0.02, which describes the match between input and 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.
