团簇态的生成

Generation of cluster states

Ping Dong, Zheng-Yuan Xue, Ming Yang, Zhuo-Liang Cao

摘要:

我们提出了两种方案的集群状态的产生。一种是基于腔量子电动力学(QED)技术。该方案只需要两个原子和单模腔之间的共振相互作用。相互作用时间非常短,这对于退相干是重要的。此外,我们还讨论了腔场衰减和原子自发发射的情况。另一种是基于原子系综。该方案具有固有的容错功能,对实际噪声和缺陷具有鲁棒性。我们计划中使用的所有设施都完全符合当前的技术。

英文摘要:

We propose two schemes for the generation of the cluster states. One is based on cavity quantum electrodynamics (QED) techniques. The scheme only requires resonant interactions between two atoms and a single-mode cavity. The interaction time is very short, which is important in view of decoherence. Furthermore, we also discuss the cavity decay and atomic spontaneous emission case. The other is based on atomic ensembles. The scheme has inherent fault tolerance function and is robust to realistic noise and imperfections. All the facilities used in our schemes are well within the current technology.
