QuTiP: Quantum Toolbox in Python

Overview

QuTiP provides comprehensive tools for simulating and analyzing quantum mechanical systems. It handles both closed (unitary) and open (dissipative) quantum systems with multiple solvers optimized for different scenarios.

Installation

uv pip install qutip

This skill targets QuTiP 5.x (verified against 5.3.0). Key v5 API changes from v4: solver options are a plain dict (the old Options/solver.Options class is gone), stochastic solvers use heterodyne=True/False instead of a noise code, and progress_bar takes a string ('text'/'tqdm'/'') rather than True.

Optional packages for additional functionality:

# Quantum information processing (circuits, gates)
uv pip install qutip-qip
