We investigate the dynamics of quantum coherence of a system consisting of two interacting atoms coupling with a common cavity which is filled with a nonlinear Kerr-like medium, in the presence of intrinsic decoherence. It is shown that the stationary quantum coherence can arise in the system as the time approach to infinite. In particular, the amount of stationary quantum coherence can be enhanced by adjusting the Kerr interaction and dipole-dipole interaction. Furthermore, we also explore the influence of Kerr interaction and dipole-dipole interaction on the transfer of quantum information by a witness of the trace distance and find that the transferred information and stationary quantum information can be controlled by the Kerr interaction and dipole-dipole interaction.

我们研究内在退相干的情况下，一个系统的量子相干动力学，该系统由两个相互作用的原子与一个公共腔耦合，该公共腔填充有非线性Kerr状​​介质。结果表明，随着时间趋于无限大，系统中会出现平稳的量子相干现象。特别地，可以通过调节Kerr相互作用和偶极-偶极相互作用来增加静态量子相干的量。此外，我们还通过跟踪距离的见证者探索了Kerr相互作用和偶极-偶极相互作用对量子信息传递的影响，发现传递的信息和固定量子信息可以通过Kerr相互作用和偶极-偶极相互作用来控制。 。
