论文摘要
我们在储层内存的影响下研究了量子相关性（QC）的动力学，作为量子信息和计算任务的资源。两级系统的量子相关性用于成功地实施量子传送，并研究在噪音环境的影响下，愿传态性忠诚度，违反贝尔 - 奇克不平等，量子转向和纠缠之间的关系如何相互联系。马尔可夫和非马克维亚通道都被考虑，这表明相关的衰减和复兴遵循状态空间中量子相关的层次结构。在有和没有记忆的情况下，检查了不同类型的Unital量子通道的量子相关性的噪声耐受性。量子速度限制时间$（τ_{qsl}）$从量子噪声的内存的角度研究，并使用相应的动力学来分析量子相关的演变。我们建立了信息回流，量子速度限制时间与非马克维亚量子通道的量子相关性的动力学之间的连接。
We investigate the dynamics of quantum correlations (QC) under the effects of reservoir memory, as a resource for quantum information and computation tasks. Quantum correlations of two-qubit systems are used for implementing quantum teleportation successfully, and for investigating how teleportation fidelity, violation of Bell-CHSH inequality, quantum steering and entanglement are connected with each other under the influence of noisy environments. Both Markovian and non-Markovian channels are considered, and it is shown that the decay and revival of correlations follow the hierarchy of quantum correlations in the state space. Noise tolerance of quantum correlations are checked for different types of unital and non-unital quantum channels, with and without memory. The quantum speed limit time $(τ_{QSL})$ is investigated from the perspective of memory of quantum noise, and the corresponding dynamics is used to analyze the evolution of quantum correlations. We establish the connection between information backflow, quantum speed limit time and dynamics of quantum correlations for non-Markovian quantum channels.
