论文摘要
失散的系统可以自发实现同步动力学，并在不同的本地和全局耗散方案中显示出鲁棒的量子相关性。超出马尔可夫限制，从环境中的信息回流成为一种至关重要的机制，其与自发同步的相互作用尚不清楚。考虑到两个耦合量子位的模型，其中一个与耗散环境相互作用，我们表明非马克维亚性对同步的出现非常有害，因为由于存在信息回流，后者可能会延迟和阻碍。根据重复交互的主方程方法和碰撞模型，获得了结果，这代表了一种非常多功能的工具来定制所需的环境。
Detuned systems can spontaneously achieve a synchronous dynamics and display robust quantum correlations in different local and global dissipation regimes. Beyond the Markovian limit, information backflow from the environment becomes a crucial mechanism whose interplay with spontaneous synchronization is unknown. Considering a model of two coupled qubits, one of which interacts with a dissipative environment, we show that non-Markovianity is highly detrimental for the emergence of synchronization, for the latter can be delayed and hindered because of the presence of information backflow. The results are obtained considering both a master equation approach and a collision model based on repeated interactions, which represents a very versatile tool to tailor the desired kind of environment.
