The decoherence dynamics of multipartite entanglement in a non-Markovian environment

Zhi He, Jian Zou, Bin Shao +1 more

We consider four two-level atoms interacting with independent non-Markovian reservoirs with detuning. We mainly investigate the effects of the detuning and the length of the reservoir correlation time on the decoherence dynamics of multipartite entanglement. We find that the time evolution of the entanglement of atomic and reservoir subsystems is determined by a parameter which is a function of the detuning and the reservoir correlation time. We also find that the decay and revival of the entanglement of the atomic and reservoir subsystems are closely related to the sign of the decay rate. We also show that the cluster state is the most robust to decoherence compared with Dicke, GHZ and W states for this decoherence channel.We consider four two-level atoms interacting with independent non-Markovian reservoirs with detuning.

Generation of long-living entanglement between two distant three-level atoms in non-Markovian environments

Chuang Li, Sen Yang, Jie Song +2 more

In this paper, a scheme for the generation of long-living entanglement between two distant Λ-type three-level atoms separately trapped in two dissipative cavities is proposed. In this scheme, two dissipative cavities are coupled to their own non-Markovian environments and two three-level atoms are driven by the classical fields. The entangled state between the two atoms is produced by performing Bell state measurement (BSM) on photons leaving the dissipative cavities. Using the time-dependent Schördinger equation, we obtain the analytical results for the evolution of the entanglement. It is revealed that, by manipulating the detunings of classical field, the long-living stationary entanglement between two atoms can be generated in the presence of dissipation.In this paper, a scheme for the generation of long-living entanglement between two distant Λ-type three-level atoms separately trapped in two dissipative cavities is proposed.
