Note This harness system is in an early stage and evolving fast. Harnessing Quantum 2026 participants: this is the repository you work in and send your pull request to — start with Start Here below. A formal release is planned for August 2026.
A computational quantum research harness. It helps an AI agent to run the simulation of quantum systems. Each method is curated by world-leading experts in that computational approach, so the guidance reflects real research practice: what to compute, which checks matter, and where common failures happen.
The Harness provides:
- Model cards with Hamiltonians, symmetries, etc
- Numeric methods and tool-usage skills with parameters setup guidance, computational resource estimation, and verification checks.
- Supporting skills for research survey, report writing, paper reproduction.
- Cluster support for calculations too large for a laptop.
If you do not yet have Claude Code, Codex CLI, or OpenCode installed, follow the summer-school agent setup guide first.
Paste this into Claude Code, Codex, or OpenCode:
Clone https://github.com/QuantumBFS/quantum.harness.
Run `/onboard` and `make skills` to install necessary dependencies.
Then run `/beginner-training` skill to start the guided training.
Each method is curated by world-leading experts in that computational approach.
