Comparative explorations of the revival and robustness for quantum dynamics under decoherence channels

In this paper, we demonstrate the revival and robustness of quantum dynamics under local decoherent evolutions through investigating the dynamical behaviors of quantum correlation. The results show that in depolarizing channel, quantum discord damps faster and revivals after a dark interval of time, while the others will revival immediately at the critical point. In addition, in hybrid channel the declining initial condition can speed up the attenuation of quantum discord within a limited time, while it can enable trace distance discord and Bures distance discord to damp more smoothly. In this sense, quantum discord is typically less robust against decoherence than the others. Interestingly, nonlocality shows different decay rates in the vicinity of critical point. Additionally, we lastly provide a physical interpretation concerning these phenomena.
