Add this skill

Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/K-Dense-AI/scientific-agent-skills.git
cp -r scientific-agent-skills/skills/cirq ~/.claude/skills/cirq   # personal, or .claude/skills in a project

In the Claude apps, zip the cirq folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/K-Dense-AI/scientific-agent-skills.git
cp -r scientific-agent-skills/skills/cirq .agents/skills/cirq   # repo; ~/.agents/skills for all projects

Standalone skills also load in the ChatGPT desktop app.

Cursor

Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:

git clone --depth 1 https://github.com/K-Dense-AI/scientific-agent-skills.git
cp -r scientific-agent-skills/skills/cirq .cursor/skills/cirq   # project; ~/.cursor/skills for all projects

What this skill does

Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. Best for Google hardware, noise modeling, and low-level circuit design. For IBM hardware use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip. Cirq is Google Quantum AI's open-source framework for designing, simulating, and running quantum circuits on quantum computers and simulators.

When it triggers

  • Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments.
  • use qiskit; for quantum ML with autodiff use pennylane; for physics simulations use qutip.
