In this paper, we outline a scheme for entanglement swapping based on the concept of
cavity QED. The atom–field entangled state in our study is produced in the nonlinear regime …

The engineering of Kerr and time-dependent coupling interactions is of great attention for
treating quantum information in quantum systems and for investigating the collective …

An entangled state, as an essential tool in quantum information processing, may be
generated through the interaction between light and matter in cavity quantum …

In this paper, a model in which two moving atoms interact with a two-mode field with
nondegenerate two-photon transitions is studied in the presence of intensity-dependent …

In this paper, we investigate the possibility of entanglement swapping between two
independent nonperfect cavities consisting of an atom with finite lifetime of atomic levels (as …

We present a general problem of quantum entanglement quantified by von Neumann
entropy for N-level atomic system. Time evolution of state vector of the entire system is …

In this paper, we present a model which exhibits two identical Ξ-type three-level atoms
interacting with a single-mode field with k-photon transition in an optical cavity enclosed by a …

In the present work, we examine qualitatively the entanglement and parameter estimation in
a two superconducting qubits (SC-qubits) coupled to a nonlinear field in the existence of …

In this paper, we study the interaction between two two-level atoms and two coupled modes
of a quantized radiation field in the form of parametric frequency converter injecting within an …

The interaction between a◊-type four-level atom and a single-mode field in the presence of
Kerr medium with intensity-dependent coupling involving multi-photon processes has been …
