局域Lindblad演化下的纠缠动力学

Entanglement dynamics under local Lindblad evolution

Sandeep K. Goyal, Sibasish Ghosh

摘要:

在有限维复合开放系统中的纠缠突然死亡(ESD)的现象在这里描述的两个二部以及多部的情况下,其中个别子系统进行Lindblad型热浴演化。ESD被认为是通用的非零温度的浴。在T=0时,热浴对两个量子比特的纯纠缠态的单侧作用不显示ESD。

英文摘要:

The phenomenon of entanglement sudden death (ESD) in finite dimensional composite open systems is described here for both bi-partite as well as multipartite cases, where individual subsystems undergo Lindblad type heat bath evolution. ESD is found to be generic for non-zero temperature of the bath. At T=0, one-sided action of the heat bath on pure entangled states of two qubits does not show ESD.
