后验隐形传态
A posteriori teleportation
摘要：
Bouwmeester等人关于实验量子隐形传态的文章构成了新兴的量子信息领域的一个重要进展。这个实验的动机是Bennett等人的提议，在这个提议中，一个未知的量子态被Alice“传送”给Bob。如图1所示，在Bouwmeester等人实施该过程时，如在原始协议中，输入量子态被“非实体化”为量子和经典分量。然而，与原始方案相比，Bouwmeester等人。的过程必然会破坏鲍勃接收终端的状态，因此“远距传送”状态永远无法作为自由传播状态出现以供后续检查或利用。事实上，心灵传输只是作为一种后验而实现的。
英文摘要：
The article by Bouwmeester et al. on experimental quantum teleportation constitutes an important advance in the burgeoning field of quantum information. The experiment was motivated by the proposal of Bennett et al. in which an unknown quantum state is `teleported' by Alice to Bob. As illustrated in Fig. 1, in the implementation of this procedure, by Bouwmeester et al., an input quantum state is `disembodied' into quantum and classical components, as in the original protocol. However, in contrast to the original scheme, Bouwmeester et al.'s procedure necessarily destroys the state at Bob's receiving terminal, so a `teleported' state can never emerge as a freely propagating state for subsequent examination or exploitation. In fact, teleportation is achieved only as a postdiction.
