QuTiP 5 Scope Use QuTiP for finite-dimensional quantum mechanics, quantum optics, Lindblad dynamics, trajectories, weak-coupling Bloch-Redfield models, and specialized Floquet, HEOM, and permutational-invariance methods. It is not a hardware execution SDK. Circuit and control functionality moved to separate QuTiP family packages. This skill targets QuTiP 5.3.1 , released 2026-08-04. QuTiP 5.3 requires Python 3.11 or newer. Its required distributions are NumPy ( ), SciPy ( , excluding and ), and .
