含时密度算子的算子和表示及其应用
Operator-sum representation of time-dependent density operators and its applications
摘要：
我们证明了开放系统的任意含时密度算符都可以用算符和表示来描述，而不管它的初始条件和在状态空间中的演化路径如何，并给出了$N$维系统的任意含时密度算符的Kraus算符的一般表达式.最后通过几个例子说明了所得结果的应用.
英文摘要：
We show that any arbitrary time-dependent density operator of an open system can always be described in terms of an operator-sum representation regardless of its initial condition and the path of its evolution in the state space, and we provide a general expression of Kraus operators for arbitrary time-dependent density operator of an $N$-dimensional system. Moreover, applications of our result are illustrated through several examples.
