导出了非马尔可夫量子随机输运过程累积量母函数(CGF)的一般表达式。CGF的长时间限制是由记忆核预解的一个控制极点决定的，我们利用递归方法从该控制极点提取电流的零频累积量。有限频率噪声不仅用预解决方案来表示，而且还用系统-环境的初始相关来表示。作为一个例子，我们考虑电子通过耗散双量子点的输运，研究耗散对高阶零频累积量和有限频噪声的影响。

英文摘要：
We derive a general expression for the cumulant generating function (CGF) of non-Markovian quantum stochastic transport processes. The long-time limit of the CGF is determined by a single dominating pole of the resolvent of the memory kernel from which we extract the zero-frequency cumulants of the current using a recursive scheme. The finite-frequency noise is expressed not only in terms of the resolvent, but also initial system-environment correlations. As an illustrative example we consider electron transport through a dissipative double quantum dot for which we study the effects of dissipation on the zero-frequency cumulants of high orders and the finite-frequency noise.
