Broadcasting of entanglement in three-particle GHZ state via quantum copying
Zhao-Yang Tong, Le-Man Kuang
We introduce entanglement measures to describe entanglement in a three-particle system and apply it to studying broadcasting of entanglement in three-particle GHZ state. We show th…
Tunneling Dynamics of Bose-Einstein Condensates with Feshbach Resonances
Bambi Hu, Le-Man Kuang
We study tunneling dynamics of atomic pairs in Bose-Einstein condensates with Feshbach resonances. It is shown that the tunneling of the atomic pairs depends on not only the tunnel…
Excitation spectrum of three dressed Bose-Einstein condensates
Zhong-Wen Ouyang, Le-Man Kuang
We study quantum dynamics of three dressed Bose-Einstein condensates in a high-Q cavity. The quasiparticle excitation spectrum of this system is found numerically. The stability of…
Macroscopic quantum self-trapping and atomic tunneling in two-species Bose-Einstein condensates
Le-Man Kuang, Zhong-Wen Ouyang
We present a new theoretical treatment of macroscopic quantum self-trapping (MQST) and quantum coherent atomic tunneling in a zero-temperature two-species Bose-Einstein condensate…
Nonlinear Decoherence in Quantum State Preparation of a Trapped Ion
Le-Man Kuang, Hao-Sheng Zeng, Zhao-Yang Tong
We present a nonlinear decoherence model which models decoherence effect caused by various decohereing sources in a quantum system through a nonlinear coupling between the system a…
Decoherence in Two Bose-Einstein Condensates
Le-Man Kuang, Zhao-Yang Tong, Zhong-Wen Ouyang +1
In this paper, decoherence in a system consisting of two Bose-Einstein condensates is investigated analytically. It is indicated that decoherence can be controlled through manipula…
