Query: 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.
