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.
