Entanglement and Its Dynamics with Atomic Spontaneous Decay

H. A. Hessian, A.‐B. A. Mohamed

Published Jul 1, 2008• 3 citations
Publisher

Abstract

The atomic decay for a two-level atom interacting with a single mode of electromagnetic field is considered. For a chosen initial state, the exact solution of the master equation is found. Therefore, effect of the atomic damping on entanglement (purity loss), degree of entanglement by the negativity, mutual information and atomic coherence through the master equation are studied.

Effect of atomic decay on purity, total correlations and entanglement of pure and mixed states

H. A. Hessian

The atomic decay for a two level atom interacting with a single mode of electromagnetic field is considered. In particular for a coherent state or statistical mixture (SM) of two opposite coherent states as initial field states, the exact solution of the master equation is found. Effect of the atomic damping on the partial entropies of the atom or the field and the total entropy as a measures of the purity loss is investigated. The degree of entanglement by the negativity and the mutual information and the atomic coherence through the master equation is studied.

Abstract: The effect of atomic spontaneous decay is considered for a two-level atom interacting with a single mode of electromagnetic field.The exact solution of the master equation is found for a chosen initial state. We study the effects of atomic decay on information and entanglement through temporal evolution of atomic quantum Fisher information, partial entropy of the atom and negativity.

ENTROPY GROWTH AND DEGRADATION OF ENTANGLEMENT DUE TO DAMPING OF THE ATOMIC DECAY IN THE JC MODEL

H. A. Hessian

In this presentation, we considered the atomic decay (but not for the cavity) for a two-level atom interacting with a single mode of electromagnetic field. The exact solution of the master equation in the case of a high-Q cavity with atomic decay is found. The effects of the atomic damping for a thermal reservoir on the temporal evolution of partial entropies of the atom or the field, and the total entropy as a quantitative entanglement, was measured. The degree of entanglement, through the sum of the negative eigenvalues of the partially transposed density matrix and the negative mutual information, has been studied and compared with other measures.

Effects of cavity damping on the entanglement for a three-level atomic system

A.‐S. F. Obada, H. A. Hessian, A.‐B. A. Mohamed

Based on the master equation for the density matrix, the dynamics of the entanglement of the three-level atom interacting with single-mode field in a finite-Q cavity are studied. It was found that the cavity damping leads to growing entropy and a strong degradation of the entanglement, therefore the coherence loss and entanglement is very sensitive to any change in the cavity damping parameter.

The effect of atomic spontaneous decay on the dynamics of the negativity of the Wigner function of radiation

Abdel‐Baset A. Mohamed

The exact solution of the master equation for the case of a high- Q cavity with atomic decay is found. We use the negativity of the Wigner function (WF) as an indicator of nonclassicality. It is found that the negative values of the field WF are very sensitive to any change in the damping parameter. The atomic spontaneous decay leads to the simultaneous disappearance of both entanglement and nonclassicality of quantum states. Moreover, the purity of the field states is completely lost.

Entropies and entanglement for decoherence without energy relaxation in a two-level atom

A.‐S. F. Obada, H. A. Hessian, A-B A Mohamed

In this paper, we investigate the temporal evolution of various measures of degree of entanglement and total correlation of a single-mode light field interacting with a two-level atom. The phase-damped cavity is taken into account. The effects of phase damping on a temporal of partial entropies for the atom and the field, total entropy, the entropy difference and the sum of negative eigenvalues of the partially transposed density matrix as a quantitative entanglement measure for the master equation in the dressed-state approximation are taken into account.
