摘要
研究了振幅阻尼通道中两个三能级原子系统的可提纯性演化现象。结果表明,自由纠缠态保持时间比束缚纠缠态的更长,与以前的研究结果相比存在较大差异。自由纠缠态直接演化至可分离态,所提模型中未出现可提纯性猝死现象。
Abstract
The distillability evolution of qutrit-qutrit systems in an amplitude damping channel is investigated. The research results show that the lasting time of free entangled states is longer than that of bound entangled states, which is quite different from the former results. The free entangled states evolve to the separable states directly, and the sudden death phenomenon of distillability is not observed in the proposed model.
