Simple schemes for generation of W-type multipartite entangled states and realization of quantum-information concentration
《Chinese Physics B》2010年第10期114-119,共6页张登玉 唐世清 谢利军 詹孝贵 陈银花 高峰 
Project supported by the Key Scientific Research Fund of the Educational Department of Hunan Province of China (Grant No. 09A013);Science Foundation of Hengyang Normal University of China (Grant No. 09A28)
We propose simple schemes for generating W-type multipartite entangled states in cavity quantum electrodynamics （CQED）. Our schemes involve a largely detuned interaction of A-type three-level atoms with a single-mod...

W-State Generation and Manipulation for Ion-Trap-Based Quantum-Information Processing
《Communications in Theoretical Physics》2010年第1期63-66,共4页贾竹君 汪新文 汪志勇 
Supported by the Natural Science Foundation of Hunan Province under Grant No.06JJ50015
We propose an ion-trap scheme for one-step generation of a special configuration of W-class state which has recently been shown to be better than canonical W states for several quantum-information processing tasks. We...

Faithful Controlled Teleportation of an Arbitrary Unknown Two-Atom State via Special W-States and QED Cavity被引量：2
《Communications in Theoretical Physics》2008年第5期1199-1202,共4页WANG Ya-Hong SONG He-Shan YU Chang-Shui 
The project supported by National Natural Science Foundation of China under Grant Nos.60472017,10575017,and 10704011;Science Foundation of the Educational Department of Laioning Province under Grant No.2006B014
A scheme is proposed for the controlled teleportation of an arbitrary two-atom state via special W-type entangled states and QED cavity. The scheme does not involve the direct joint Bell-state-measurement （BSM）. We ...
