QSW_MPI: A framework for parallel simulation of quantum stochastic walks

QSW_MPI is a Python package developed for time-series simulation of continuous-time quantum stochastic walks. This model allows for the study of Markovian open quantum systems in the Lindblad formalism, including a generalisation of the continuous-time random walk and continuous-time quantum walk. Consisting of a Python interface accessing parallelised Fortran libraries utilising sparse data structures, QSW_MPI is scalable to massively parallel computers, which makes possible the simulation of a wide range of walk dynamics on directed and undirected graphs of arbitrary complexity.QSW_MPI是一款专为连续时间量子随机游走（continuous-time quantum stochastic walks）的时序模拟开发的Python包。该模型可依托林德布拉德形式主义（Lindblad formalism）开展马尔可夫开放量子系统的研究，涵盖了连续时间随机游走与连续时间量子游走的一般化推广形式。QSW_MPI搭载Python接口，可调用采用稀疏数据结构的并行化Fortran库，能够适配大规模并行计算机，从而支持对任意复杂度的有向与无向图上的各类游走动力学进行模拟。
