Yuan, Yang Hao, Quan Quan +1 more

为在洞证完一个任意的未知 single-qubit 状态分享的概括的量状态的一个试验性地可行的计划被介绍。用在三之中的量隧道狂欢的一个概括 Greenberger Horne Zeilinger (GHZ ) 状态，量信息(即 single-qubit 状态) 如果并且仅当两接收装置协作，从发送者，罐头以如此的一个方法被切开，信息能被恢复。而且，计划对两个感觉迟钝热地和洞的效果腐烂。

We consider the entanglement dynamics of three two-level atoms interacting with independent structured non-Markovian reservoirs. The atoms are initially prepared in a mixed multipartite Greenberger—Horne—Zeilinger (GHZ)-type state. Based on the purity and non-Markovian reservoirs, we show that the reservoirs' entanglement can exhibit not only multipartite entanglement sudden birth but also entanglement sudden death, and the revival of atom entanglement is not always accompanied by the disentanglement of reservoirs. Meanwhile, we derive the quantitative criteria for multipartite revival and death phenomena and find multipartite entanglement sudden death and entanglement sudden birth simultaneous apparition time is independent of the initial three-qubit state.We consider the entanglement dynamics of three two-level atoms interacting with independent structured non-Markovian reservoirs.

使用空间纠纷在现实主义的环境由在自由的不同的度之间的纠纷转变净化极化纠纷的协议被详细描述。我们的分析证明小点扭动错误能完全被净化，但是如果空间纠纷是掺杂的，纯最大地纠缠的状态不能最终被获得。净化的状态的忠实被空间纠纷决定。而且，这个协议能也被扩大净化多粒子 Greenberg -- Horne -- Zeilinger (GHZ ) 状态。空间纠纷能作为另一来源被服务改进纠纷的质量，这被介绍。[从作者抽象]使用空间纠纷在现实主义的环境由在自由的不同的度之间的纠纷转变净化极化纠纷的协议被详细描述。我们的分析证明小点扭动错误能完全被净化，但是如果空间纠纷是掺杂的，纯最大地纠缠的状态不能最终被获得。净化的状态的忠实被空间纠纷决定。而且，这个协议能也被扩大净化多粒子 Greenberg -- Horne -- Zeilinger (GHZ ) 状态。空间纠纷能作为另一来源被服务改进纠纷的质量，这被介绍。[从作者抽象]

当纠缠的量系统之一与记忆效果被联合到一座本地水库时，量纠纷的 non-Markovian 动力学被 ShabaniLidar 主人方程学习。完全积极的减少的动态地图能在 Kraus 表示被构造。量纠纷在 non-Markovian 环境更慢慢地腐烂。量纠纷的 decoherence 时间能显著地与存储器内核的变化被增加。这被发现纠纷在量系统和纠纷之间的突然的死亡在系统和水库之间的突然的出生发生在不同片刻。
