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的时间序列模拟而开发的Python软件包。该模型允许可马尔可夫的开量子系统在林德布莱德公理框架下进行研究，包括对连续时间随机游走和连续时间量子游走的推广。QSW_MPI由一个Python接口组成，该接口访问利用稀疏数据结构的并行化Fortran库，具有可扩展至大规模并行计算机的能力，这使得在任意复杂性的有向和无向图上模拟广泛的游走动力学成为可能。
