What problem does it solve?

QuTiP provides a comprehensive framework to simulate open quantum systems and their dynamics, enabling researchers to model dissipation, decoherence, and driven quantum systems without building bespoke solvers.

Core Features & Use Cases

• Quantum object management and tensor products with Qobj-based states and operators.
• Time evolution solvers for closed and open systems (sesolve, mesolve, mcsolve, brmesolve, fmmesolve) with optional time-dependent Hamiltonians.
• Analysis and visualization utilities for expectation values, entropy, fidelity, correlations, and steady states.
• Use Case: Model a damped Jaynes-Cummings system to study photon exchange and dissipation under Lindblad dynamics.

Quick Start

Define a simple two-level system with a Hamiltonian and collapse operators, run sesolve or mesolve, and plot ⟨n⟩ over time.
