论文摘要
当记忆效应在其演变过程中发生时,量子过程称为非马克维亚。量子非马克维亚性是一种通常与从环境到主要系统的后流相关的现象,但是已经表明,这种效果不是必需的。在这项工作中,我们在离散和连续变量系统中建立了量子非马克维亚性与量子传送方案之间的联系。我们还展示了主要系统与环境之间的传送协议期间的信息如何以双向方式导致国家复兴。
A quantum process is called non-Markovian when memory effects take place during its evolution. Quantum non-Markovianity is a phenomenon typically associated with the information back-flow from the environment to the principal system, however it has been shown that such an effect is not necessary. In this work, we establish a connection between quantum non-Markovianity and the protocol of quantum teleportation in both discrete and continuous-variable systems. We also show how information flows during a teleportation protocol between the principal system and the environment in a bidirectional way leading up to a state revival.
