摘要
一个计划被建议因为经由特殊 W 类型的一个任意的二原子的状态的控制远距传物纠缠了状态和证完洞。计划不包含直接联合的 Bell-state-measurement (BSM ) 。我们证明量信息被分成二部分，没有另外的代理人的合作和古典通讯，因此，原来的原子状态不能被接收装置完美地恢复。另外，这个计划的物理实现不是困难的。
A scheme is proposed for the controlled teleportation of an arbitrary two-atom state via special W-type entangled states and QED cavity. The scheme does not involve the direct joint Bell-state-measurement （BSM）. We show that the quantum information is split into two parts~ thus the original atomic state cannot be perfectly restored by the receiver without the other agent＇s collaboration and classical communication. In addition, the physical realization of this scheme is not difficult.
