Abstract:
The dynamics of quantum steering property of quantum correlated state is investigated in cavity QED systems coupled to structured environments. The quantum decoherence from the interactions between the system and its surrounding can be described by the quantum noisy channel. From the geometric point of view, the deformation and volume of quantum steering ellipsoid are analyzed to evaluate the dynamics of quantum steering of bipartite quantum entangled states. The effects of quantum decoherence on the asymmetric property of quantum steering are studied. It is found that the environmental noise results in the manifest deformation of quantum steering ellipsoid whose volume is decreased. When the bipartite systems are subjected to the quantum noise from the structured reservoir, the formation is drastically squeezed. In the case of strong couplings between the systems and environments, the rapid decrease of the volume of the ellipsoid happens with the time.
