摘要
为一个未知二原子的纠缠的状态的远距传物的一个试验性地可行的计划被建议。我们的计划把一个簇状态用作量隧道，在我们不需要任何联合钟状态测量的地方。而且远距传物罐头的成功的概率和忠实两个都到达 1.0。当前的计划能在当前的试验性的技术以内被认识到。
An experimentally feasible scheme for teleportation of an unknown two-atom entangled state is proposed. Our scheme uses a duster state as the quantum channel, where we do not need any joint Bell-state measurement. Moreover the successful probability and fidelity of teleportation can both reach 1.0. The current scheme can be realized within the current experimental technology.
