QuTiP: The Quantum Toolbox in Python

QuTiP is an open-source Python library for simulating the dynamics of closed and open quantum systems. It provides user-friendly and efficient numerical simulations for a wide range of quantum mechanical problems, including those with arbitrary time-dependence, commonly found in quantum optics, trapped ions, superconducting circuits, and quantum nanomechanical resonators. The library, currently at version 5.2.3, is built upon NumPy, SciPy, and Cython for numerical backends and Matplotlib for graphical output, with regular minor and patch releases, and significant major updates.
