Lower and upper bounds for entanglement of Rényi- entropy
Wei Song, Lin Chen, Zhuo-Liang Cao
Entanglement Rényi- entropy is an entanglement measure. It generalizes the entanglement of formation, and they coincide when tends to 1. We derive analytical lower and upper…
Sudden death and robustness of quantum discord and entanglement of two atoms in dissipative cavities in dispersive limit
Jian-Song Zhang, Lin Chen, M. Abdel-Aty +1
The quantum dynamics of two entangled two-level atoms initially in extended Werner-like (EWL) states is studied. Each of the two atoms is located within an isolated and dissipative…
Dynamics of quantum discord in the purification process
Wei Song, Lin Chen, Ming Yang +1
We investigate the dynamics of quantum discord during the purification process. In the case of Werner states, it is shown that quantum discord is increased after a round of purific…
Sudden death of distillability in qutrit-qutrit systems
Wei Song, Lin Chen, Shi-Liang Zhu
We introduce the concept of distillability sudden death, i.e., free entangled states can evolve into non-distillable (bound entangled or separable) states in finite time under loca…
