qutip
Quantum physics simulation library for open quantum systems. Use when studying master equations, Lindblad dynamics, decoherence, quantum optics, or cavity QED. Best for physics research, open system dynamics, and educational simulations. NOT for circuit-based quantum computing—use qiskit, cirq, or pennylane for quantum algorithms and hardware execution.
npx skills add LeonChaoX/qinyan-academic-skills --skill qutip --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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 ```bash uv pip install qutip ``` Optional packages for additional functionality: ```bash # Quantum information processing (circuits, gates) uv pip install qutip-qip # Quantum trajectory viewer uv pip install qutip-qtrl ``` ## Quick Start ```python from qutip import * import numpy as np import matplotlib.pyplot as plt # Create quantum state psi = basis(2, 0) # |0⟩ state # Create operator H = sigmaz() # Hamiltonian # Time evolution tlist = np.linspace(0, 10, 100) result = sesolve(H, psi, tlist, e_ops=[sigmaz()]) # Plot results plt.plot(tlist, result.expect[0]) plt.xlabel('Time') plt.ylabel('⟨σz⟩') plt.show() ``` ## Core Capabilities ### 1. Quantum Objects and States Create and manipulate quantum states and operators: ```python # States psi = basis(N, n) # Fock state |n⟩ psi = coherent(N, alpha) # Coherent state |α⟩ rho = thermal_dm(N, n_avg) # Thermal density matrix # Operators a = destroy(N) # Annihilati

What does the qutip skill do?
Quantum physics simulation library for open quantum systems. Use when studying master equations, Lindblad dynamics, decoherence, quantum optics, or cavity QED. Best for physics research, open system dynamics, and educational simulations. NOT for circuit-based quantum computing—use qiskit, cirq, or pennylane for quantum algorithms and hardware execution.
How do I install it?
Run `npx skills add LeonChaoX/qinyan-academic-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 LeonChaoX/qinyan-academic-skills, a repository with 759 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.
