Three-Qubit Entanglement Sudden Death
Communications in Theoretical Physics, 2008We study entanglement dynamics of three-qubit system via negativity. Three atoms A, B, and C interact isolatedly with their own Jaynes–Cummings cavities a, b, and c. Aa system is prepared entangled with Bb and Cc, however, their mutual isolations forbid Aa interacting with system Bb and Cc. It is the same for system Bb and Cc.

Entanglement sudden death in a spin channel
Journal of Physics A: Mathematical and Theoretical, 2007We study the dynamic evolution of the entanglement in a spin channel with an XY-type interaction initially in an entangled state. We find that the phenomenon of entanglement sudden death (ESD) appears in the evolution of entanglement for some initial states.

ENTANGLEMENT TRAPPING AND SUDDEN DEATH IN A COMMON BAND GAP
International Journal of Quantum Information, 2011Using the pseudomode method, we study the exact entanglement dynamics of two atoms in a common band gap. In order to understand the role played by the common band gap we compare our results with the case of two independent band gap model. We demonstrate that the parameter region at which the entanglement sudden death occurs is smaller than the ...

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.

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 ...

Pre-management of Entanglement Sudden Death
The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013We report a summary of our work on management of entanglement sudden death (ESD) through initial conditions. ESD phases are shown for a generic two-qubit system that undergoes local but unbalanced amplitude damping dissipations.

Observation of the entanglement sudden death
2008We demonstrate, using an all-optical setup, the difference between local and global dynamics of entangled quantum systems coupled to independent environments. Even when the decay of each system is asymptotic, quantum entanglement may suddenly disappear.
