| 摘 要： | 提出了一个利用一个两粒子最大纠缠相干态和一个三粒子纠缠相干态作为量子信道进行三粒子纠缠相干态隐形传态的方案.该方案只需线性光学操作和双模光子数测量.计算结果表明,应用本方案的设置,隐形传态成功的概率与所用的相干态的平均光子数有关,反映了纠缠相干态的非正交特性.

| Abstract: | A scheme for teleportation of a tripartite entangled coherent state is proposed by using a bipartite maximally entangled coherent state and a tripartite entangledcoherent state with bipartite maximal entanglement as quantum channels. The scheme is based on linear optical operations and two mode photonnumber measurements. It is found that with this setup the probability of successful teleportation depends on the mean photon number of the coherent state. It reflects the nonorthogonal properties of the entangled coherent states. |
