Three-Atom Entanglement Sudden Death and Birth in Cavity QED with the Influence of the Stark Shift
Kun Hua Wu, Qing Feng Huang, Xiao Qing Zhang · Advanced materials research · 2013
We investigate the entanglement dynamics in a quantum system consisting of three two-level atoms interacting with three spatially separated cavities with the influence of the Stark shift, and we can find that the entanglement sudden death (ESD) and birth (ESB) will be improved by adjusting the Stark parameters. When we choose the appropriate Stark parameters, the phenomena of ESD and ESB will be appeared, but, which will appear earlier than the other depends on the Stark-shift values.
