Decay and survivability of entanglement in two-dimensional ionic motions
This contribution describes some new features of quantum entanglement in a single three-level trapped ion confined in a two-dimensional (2D) harmonic potential. The dynamical properties of quantum entanglement are studied ...
Quantum information entropy and multi-qubit entanglement
The exciting new features of entanglement are burgeoning with revolutionary new advances in the areas of quantum communication, quantum information processing and quantum computing. We review recent theoretical studies and ...
Engineering transient spectrum for a two-level system interacting with two-mode intelligent states
The problem of a single two-level atom in its excited state, placed in a bimodal cavity in which an arbitrary form of the intensity-dependent atom-field coupling is present, is solved exactly. Expressions for the energy ...
Manipulating mixed state entanglement between a time-dependent field and a three-level trapped ion
In this paper, we extend earlier investigations (Q.C. Zhou, S.N. Zhu, Opt. Commun. 248 (2005) 437) on the pure state entanglement to the mixed state entanglement. In particular, analysis of the pattern of entanglement ...
Quantum phase entropy and entanglement of a multiphoton three-level atom near the edge of a photonic band gap
Motivated by recent developments in quantum entanglement, we study the relations among concurrence and phase entropy of a three-level atom interacting with a bimodal cavity field. Analytical results are presented when the ...
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 ...
