Computational evaluation demonstrates classical methods outperform noisy quantum devices in fusion kinetics and materials simulation, indicating fault-tolerant architectures are necessary.
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.
