钟志荣

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]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]

Engineering Multi-atom Entangled States via Cavity Decay

Zheng Shi-Biao

A scheme is proposed for the generation of entangled states for multiple atoms trapped in a cavity by detecting photon decay. The scheme is valid no matter when the effective atom-cavity coupling strength is larger than the cavity decay rate or not, which is of importance in view of experiment. The fidelity of entanglement is insensitive to the inefficiency of the photo-detector. The scheme does not require a photon to be initially injected into the cavity.

A scheme for preparation of multi-atom entanglement by detecting the cavity decay and analysis of its implementation

L.-M. Duan, Harry J. Kimble

We give the detailed study of a scheme to efficiently engineer multi-atom entanglement by detecting the cavity decay through single-photon detectors. The scheme can be used to prepare arbitrary superpositions of multi-atom Dicke states, without the requirements of high-efficiency detection, separate addressing of different atoms, and full localization of the atoms to the Lamb-Dicke limit. We analyze in detail various sources of noise and imperfections in this experimental scheme, and show that the scheme is robust to the dominant sources of noise and realizable with the state of the art technology.We give the detailed study of a scheme to efficiently engineer multi-atom entanglement by detecting the cavity decay through single-photon detectors.

Multi-atom entanglement engineering and phase-covariant cloning via adiabatic passage

Shi‐Biao Zheng

A scheme is proposed for the generation of entangled states for multiple atoms trapped in an optical cavity via adiabatic passage. In the scheme, both the atomic system and the cavity have no probability of being excited. Thus both the atomic spontaneous emission and the cavity decay are suppressed, which makes our scheme very robust against decoherence. Taking advantage of the adiabatic process, the scheme does not require accurate adjustment of the interaction time. Furthermore, the scheme is scalable in principle. The idea can also be used for realizing phase-covariant cloning.A scheme is proposed for the generation of entangled states for multiple atoms trapped in an optical cavity via adiabatic passage.
