Entanglement of a nonlinear two two-level atoms interacting with deformed fields in Kerr medium
In this paper we investigate the entanglement dynamics between two two-level atoms interacting with two coherent fields in two spatially separated cavities which are filled with a Kerr-like medium. We examine the effect of nonlinear medium on the dynamical properties of entanglement and atomic occupation probabilities in the case of even and odd deformed coherent states. The results show that ... إقراء المزيد

Entanglement sudden death and sudden birth of an atom coupled to a bimodal lossy cavity
We propose another method for realizing entanglement sudden death and sudden birth using a single atom interacting with a bimodal cavity field in a dissipative environment. By suitably choosing the system's parameters and precisely controlling the dynamics, we find a novel connection between maximum entanglement and mixed state parameters. We discuss the intricate relationship between the entanglement dynamics and the ... إقراء المزيد

Delayed sudden birth and sudden death of entanglement in Josephson-charge qubits
Distinctive features of the entanglement dynamics of a circuit containing two-coupled superconducting charge qubits are explored. The striking effects of junction coupling on the entanglement are presented in terms of the concurrence. We also point out the importance effects of initial state selection for obtaining different features of entanglement, such as, sudden death and sudden birth. إقراء المزيد

Entanglement sudden birth of two trapped ions interacting with a time-dependent laser field
We explore and develop the mathematics of the two multi-level ions. In particular, we describe some new features of quantum entanglement in two three-level trapped ions confined in a one-dimensional harmonic potential, allowing the instantaneous position of the center-of-mass motion of the ions to be explicitly time-dependent. By solving the exact dynamics of the system, we show how survivability of ... إقراء المزيد
