Recently, a large class of quantum non-Markovian piecewise dynamics for an open quantum system obeying closed evolution equations has been introduced [1]. These dynamics have been defined in terms of a waiting-time distribution between quantum jumps, along with quantum maps describing the effect of jumps and the system evolution between them. Here, we present a quantum collision model with memory, whose reduced dynamics in the continuous-time limit reproduces the above class of non-Markovian piecewise dynamics, thus providing an explicit microscopic realization.

碰撞模型中的量子非马尔可夫分段动力学

最近，已经引入了一大类量子非马尔可夫分段动力学，用于遵循封闭演化方程的开放量子系统[1]。这些动力学是根据量子跳跃之间的等待时间分布以及描述跳跃的影响和它们之间的系统演化的量子图来定义的。在这里，我们提出了一个带有记忆的量子碰撞模型，其在连续时间限制中的减少动力学再现了上述类别的非马尔可夫分段动力学，从而提供了一个明确的微观实现。
