Qutip

QuTiP is the go-to library for simulating open quantum systems where decoherence and dissipation matter. If you're modeling cavity QED, master equations, or Lindblad dynamics, this handles the physics properly with multiple solvers optimized for different scenarios. The mesolve function for mixed states with dissipation, mcsolve for quantum trajectories, and floquet methods for driven systems cover most research needs. It's built for physicists doing actual quantum optics simulations, not gate-based quantum computing. The Hilbert space truncation and solver selection make a real difference in performance, and the Wigner function visualizations are genuinely useful for understanding what's happening in phase space.
