摘　　要：开放量子系统是指主量子系统不可避免地与其周围的环境发生耦合所形成的新的量子系统。研究了描述开放量子系统时间演化过程的两个主方程所确定的量子过程的矩阵表示,分别给出了几种特殊演化过程下矩阵表示的刻画形式,并讨论了其相关性质。Open quantum systems refer to the inevitable interaction between a quantum system and its surrounding environment.This paper studies matrix representations of the quantum process determined by the two master equations describing the time evolution process of open quantum systems.It presents the characterization forms of matrix representation under several special evolution processes,respectively.Furthermore,some properties are discussed.

关 键 词：开放量子系统 时间演化方程 矩阵表示
