# Cirq (agent skill)

> Cirq is an agent skill (a SKILL.md file) from K-Dense-AI/scientific-agent-skills. Google quantum computing framework. Use when targeting Google Quantum AI hardware, designing noise-aware circuits, or running quantum characterization experiments. It works with Claude Code, Codex, Cursor, Gemini CLI and GitHub Copilot and has 47,813 GitHub stars across a repository of 7 listed skills.

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.

## Add this skill

### Claude Code

```sh
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 skill folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

### ChatGPT / Codex

```sh
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
```

### Cursor

```sh
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
```
