Coherent and ultrafast manipulation of entanglement sudden death and recurrence
Optics Letters, 2010We investigate the entanglement dynamics of the bipartite system, consisting of two interacting two-level atoms in QED, which are driven additionally by coherent double ultrashort laser pulses characterized by various phase differences. Results show that the relative phase difference can exert significant influence on the entanglement evolution, such ...

Postponing entanglement sudden death by quantum interferences
Physica ScriptaWe investigate the entanglement dynamics in a 2 ⨂ 3 quantum system consisting of a two-level atom and a three-level V-type atom interacting independently with their environments.

Determining Separability with Entanglement of Formation and Entanglement Sudden Death
Chinese Physics Letters, 2015An algorithm is developed to calculate the entanglement of formation for bipartite quantum states to determine numerically the sufficient condition of separability. The algorithm is applied to two 3×3 positive partial transpose states mixed with white noise.

A NEW FEATURE ON THE SUDDEN DEATH OF ENTANGLEMENT
Modern Physics Letters B, 2008Based on the exactly analytic solution obtained of the intensity-dependent Jaynes–Cummings model for a certain class of initial entangled mixed states, we explore the time evolution of the entanglement between two atoms, initially non-locally correlated and separately interacting with two distinct cavities.

Experimental Demonstration of Largeness in Bipartite Entanglement Sudden Death
Chinese Physics Letters, 2011Quantum coherence is the most distinct feature of quantum mechanics. However, inevitable decoherence processes will finally destroy it and make the "Schrodinger's cat" invisible in our classical world. In this "quantum-to-classical transition", the so-called "largeness" plays a critical role.

A STUDY ON THE SUDDEN DEATH AND SUDDEN BIRTH OF ENTANGLEMENT IN AN OPEN SYSTEM
International Journal of Quantum Information, 2009In this paper, we consider the entanglement dynamics of two cavities interacting with independent reservoirs. When the cavity entanglement suddenly disappeared, the reservoir entanglement suddenly and necessarily appears. We study the effect of purity of initial entangled state of two cavities on the entanglement evolution, and acquire that the purity
