OpenQuantumSim

OpenQuantumSim is a Python interface with a Julia backend for open quantum system simulation. It is aimed at researchers who need Lindblad propagation, Monte Carlo wave-function trajectories, collective-spin/Dicke models, restartable sweeps, HDF5 outputs, and state diagnostics without leaving the Python scientific stack.
