Remote Three-Atom Information Concentration without Bell-State Measurement

Abstract

我们在洞证完为三遥远的 two-levelatoms 的信息集中建议一个计划。我们的计划不包含钟状态 measurment。在在原子和洞之间的相互作用期间,洞频率大部分是从原子转变频率的 detuned,这样计划对洞腐烂和热地感觉迟钝。这个想法能也被用来认识到套住的离子的遥远的信息集中。

Remote Three-Atom Information Concentration without Bell-State Measurement

Wu Zhen-Zhen, Mao-Fa Fang

We propose a scheme for information concentration of three remote two-level atoms in cavity QED. Our scheme does not involve the Bell-state measurement. During the interaction between atom and cavity, the cavity frequency is largely detuned from the atomic transition frequency, thus the scheme is insensitive to both the cavity decay and the thermal field. The idea can also be used to realize the remote information concentration of trapped ions.

我们建议为为在三个远洞套住的多重原子的纠缠的状态的产生的一个计划由二相同单个模式的纤维连接了。与以前的计划相比,建议计划的明显的优点是:首先,在建议协议的所有洞能自由地与对方一起交往,它在量通讯和分布式的量计算是重要的。第二,在计划,原子,洞,和纤维,模式在回声。因此,要求的相互作用时间是短的,鉴于 decoherence,它是重要的。原则上,建议计划能被扩大产生 n 原子纠缠的状态。[从作者抽象]

Remote atomic information concentration without Bell-state measurement

Wu Zhen-Zhen, Mao-Fa Fang

This paper proposes a scheme for information concentration of two remote two-level atoms in cavity QED. This scheme does not involve the Bell-state measurement. During the interaction between atom and cavity, the cavity frequency is large-detuned from the atomic transition frequency, thus the scheme is insensitive to both the cavity decay and the thermal field. This idea can directly be generalized in the case of multi-atom information concentration.

We propose a protocol of remote information concentration achieved by a four-particle cluster state. To achieve the task, Bell state measurement and unitary operation are needed. The result shows a peculiar phenomenon that the remote information concentration is not always successful but with certain probability.
