qutip
Simulate and audit closed and open quantum-system models with QuTiP 5, including deterministic, trajectory, steady-state, spectral, and phase-space workflows. Use for local quantum-dynamics work where physical assumptions, dimensions, and numerical convergence must be explicit.

Same command for any agent — swap --agent for codex, cursor, copilot.

# 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 5.3.0**, released 2026-05-22. QuTiP 5.3 requires Python 3.11 or newer. Its required distributions are NumPy (`>=1.23.2`), SciPy (`>=1.9.2`, excluding `1.16.0` and `1.17.0`), and `packaging`. ## Reproducible uv snapshot Create a dedicated environment and pin every direct distribution: ```bash uv venv --python 3.11 uv pip install "qutip==5.3.0" ``` For plots: ```bash uv pip install "qutip[graphics]==5.3.0" ``` Optional QuTiP family packages are independently versioned: ```bash uv pip install "qutip-qip==0.4.2" uv pip install "qutip-qtrl==0.2.0" uv pip install "qutip-jax==0.1.1" ``` - `qutip-qip` 0.4.2 (2026-06-23) is the production/stable circuit, gate, and noisy-device simulation package. Import from `qutip_qip`, not `qutip.qip`. - `qutip-qtrl` 0.2.0 (2026-06-23) provides GRAPE and CRAB **quantum optimal control**. It is not

What does the qutip skill do?
Simulate and audit closed and open quantum-system models with QuTiP 5, including deterministic, trajectory, steady-state, spectral, and phase-space workflows. Use for local quantum-dynamics work where physical assumptions, dimensions, and numerical convergence must be explicit.
How do I install it?
Run `npx skills add K-Dense-AI/scientific-agent-skills --skill qutip --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From K-Dense-AI/scientific-agent-skills, a repository with 32,619 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
