摘要
一个计划为近似并且有条件地，在消散的洞证完移植一个未知原子状态的电视被建议。它是计划的延期[Phys。加快。一 69 (2004 ) 064302 ] ，在洞模式腐烂没被考虑，系统进化的一个仅仅时间点和实现远距传物的相应忠实被给的地方。事实上，洞模式腐烂确实存在并且一定是 delt 与。在这篇论文，我们借助于消散的贾内斯·卡明斯模型在近似、有条件的远距传物的实现上从洞模式腐烂调查影响然后显示出远距传物的实现的忠实的分析表示。或者，我们的计划不包含一个另外的原子，仅仅要求二个原子和一个单个模式的洞。
A scheme for approximately and conditionally teleporting an unknown atomic state in dissipative cavity QED is proposed. It is the extension of the scheme of [Phys. Rev. A 69 （2004） 064302], where the cavity mode decay has not been considered and only a time point of system evolution and the corresponding fidelity implementing the teleportation are given. In fact, the cavity mode decay exists really and must be delt with. In this paper, we investigate the influence from the cavity mode decay on the implementation of the approximate and conditional teleportation by means of the dissipative Jaynes Cummings model and then show the analytical expression of the fidelity of realization of the teleportation. Alternatively, our scheme does not involve an additional atom, only requiring two atoms and one single-mode cavity.
