Abstract

一个其他的计划为一个未知原子纠缠状态的远距传物被建议。计划与 Λ-type 基于一块二模式的洞地的反响的相互作用三水平的原子。在有以前建议的计划的对比[Commun。Theor。Phys。47 (2007 ) 253 ] ，现在的计划是祖先，自从没有钟状态测量，忠实同样原则上是 1.0。计划可以被概括到 cavity-mode-entangled-state 的不仅远距传物而且处于概括 GHZ 状态包括的多原子的纠缠的状态的远距传物。并且计划基于当前的洞证完技术是试验性地可行的。

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。

Faithful Teleportation of an Unknown Atomic-Entangled State Without Bell-State Measurement

Lin Xiu, Hongcai Li, Rong‐Can Yang +1 more

An alternative scheme is proposed for teleportation of an unknown atomic-entangled state. The scheme is based on the resonant interaction of a two-mode cavity field with a Λ-type three-level atom. In contrast with the previously proposed scheme of [Commun. Theor. Phys. 47 (2007) 253], the present scheme is ascendant, since the fidelity is 1.0 in principle similarly without the Bell-state measurement. The scheme may be generalized to not only the teleportation of the cavity-mode-entangled-state but also the teleportation of the multi-atomic entangled states included in generalized GHZ states. And the scheme is experimentally feasible based on the current cavity QED technique.
