Entanglement Dynamics of Atoms in Double Jaynes—Cummings Models with Kerr Medium
Qin Xie, Mao-Fa Fang · Communications in Theoretical Physics · 2010
Entanglement dynamics of the atoms in the double Jaynes—Cummings models with the Kerr medium is studied, and the effect of the Kerr medium on that is examined. The result shows that, the Kerr medium can control the entanglement dynamics of the atoms and repress entanglement sudden death. We can obtain the maximum entanglement between the atoms by strengthening the nonlinear interaction of the Kerr medium.
