Intrinsic Decoherence of Two Atoms System With Kerr Medium
Xiaoting Zhang, Ai‐Dong Zhu, Zhang Shou · Chinese Physics Letters · 2007
We study the effect of Kerr medium on the intrinsic decoherence of a system which consists of two two-level atoms and a optical cavity. The entanglement of the system is calculated by making use of concurrence. Our results show that the intrinsic decoherence is very sensitive to the nonlinear coupling constant of Kerr medium. Both the oscillation period and the amplitude of the concurrence increase with the increasing nonlinear coupling constant.
