Nonclassical effects for a qubit coupled to a coherent two-mode cavity with intrinsic decoherence

Blog Article

In this paper, we use the su(1,1)-algebraic treatment to explore the effects of the intrinsic decoherence in a two-mode cavity containing a two-level atom.Each field is resonant with the qubit through a four-photon process.The role of the intrinsic decoherence and the superposition of the initial generalized Barut-Girardello coherent silver lining herbs kidney support state on the quantum effects is investigated via different quantifiers as: atomic inversion, linear entropy and negativity.It is found that the non-linearity of the four-photon process leads to generate non-classical effects with a high oscillatory behavior.The superposition of the Barut-Girardello coherent state controls the dynamics of the purity loss and the entanglement.

It is found that the nonclassical effects equi-jec 7 are very sensitive to the nonlinear interactions between the qubit and the two-mode cavity.
