What problem does it solve?
QuTiP helps you simulate quantum dynamics, including open-system effects like dissipation and decoherence, without manually deriving and coding bespoke numerical solvers.
Core Features & Use Cases
- Closed vs open dynamics: Simulate unitary evolution with sesolve and dissipative Lindblad/opensystem dynamics with mesolve.
- Quantum trajectories: Model stochastic evolution via mcsolve (Monte Carlo wavefunction) and more specialized non-Markovian and stochastic solvers.
- Analysis and visualization: Compute observables, entropies, fidelities, spectra/correlation functions, steady states, and generate phase-space and state visualizations (e.g., Wigner and Bloch sphere).
- Advanced modeling: Handle Floquet-driven systems, non-Markovian dynamics (e.g., HEOM), and permutation-invariant (collective) models.
Quick Start
Use QuTiP to simulate a damped harmonic oscillator by evolving an initial coherent state with mesolve using a Hamiltonian built from num(N) and collapse operators built from destroy(N).
