在这份报纸,我们建议产生四模式的簇类型的一个光计划由使用二单个光子的来源,协调州的来源,横梁 splitters,光电探测器, cross-Kerr 媒介,和阶段在免费的旅行的光地里纠缠了协调状态(ECS ) shifters。并且状态准备的成功概率被计算。最后,我们讨论如此的建议的试验性的可行性。
In this paper, we propose an optical scheme to generate four-mode cluster-type entangled coherent states (ECSs) in free traveling optical fields by using two single-photon sources, coherent state sources, beam splitters, pho- todetectors, cross-Kerr media, and phase shifters. And the success probability of the states preparation is calculated. At last we discuss the experimental feasibility of such proposal.
