四原子TaVis-Cummings模型中两体及多体纠缠的研究
A Study on Pair-wise and Multipartite Entanglement Dynamics of Four-atom Tavis-Cummings Model
摘要
Abstract
The entanglement dynamics of four two-level atoms within a single-mode cavity using concurrence and tangle is discussed. The concurrence and tangle of the system are periodic functions of time. The results show that the entanglement of the present system is restricted to the class of pair-wise entanglement. In addition, the four-qubit W state could be generated in the present model if the interaction time of the atoms and the cavity is chosen appropriately.关键词
