Abstract

We study the behaviors of quantum correlation for two atoms interacted with fluctuating electromagnetic field near a perfectly reflecting boundary. We firstly derive the master equation that governs the system evolution. Then, we discuss the generation, revival and degradation of quantum correlation, which are closely related to boundary effect and atomic polarization direction. Compared with the entanglement behaviors, it is shown that quantum correlation presents better robustness than entanglement, which may be helpful to quantum information processing. Furthermore, the presence of boundary offers us a means for preserving quantum correlation under decoherence and gives us more freedom to adjust the behaviors of quantum correlation.
