# Quantum Simulation of Fusion Kinetics and Materials, Honestly: 5-Qubit Landau Damping, ADAPT-VQE at Chemical Accuracy, and the Resource Frontier

**Authors:** Ford, P I

## Summary

Quantum computing for fusion, with honest resource estimates. Landau damping reproduced on a five-qubit Hamiltonian-simulation circuit; ADAPT-VQE at chemical accuracy on the candidate fusion-alloy fragments; and a resource frontier separating the tractable linear kinetic operator (early fault-tolerant) from the nonlinear gyrokinetic problem (fault-tolerant horizon). Noisy hardware shows no advantage today; classical gyrokinetics remains cheaper at every demonstrated scale.

## What's in this repository

- `*_Editorial_2026.pdf` — the editorial edition of the paper.
- `*_reproducibility_bundle.zip` — the reproducibility bundle: toolkit source, the per-gate runs the paper cites, and a student pack (concept notes, tutorial, glossary, `reproduce.ipynb`, `requirements.txt`).

## Reproduce

```bash
unzip *_reproducibility_bundle.zip -d bundle && cd bundle
pip install -r requirements.txt
jupyter notebook reproduce.ipynb
```

## Scope

Physics and engineering only; no economics. Every quantity traces to a documented gate in the KRONOS de-risking register. Honest gates are stated in the paper.
