Physics-Informed AI and Quantum Technologies for Certifiable Real-Time Control of Compact Fusion Generators

A layered digital-twin control architecture holding three technology-readiness tiers apart. A control-barrier safety clamp gives a provable zero-escape guarantee on the reduced-order operating envelope; quantum sensing is near-term diagnostics; quantum computation is an offline calibration tier with no resource crossover this decade. Every result is on a physics-based twin, on public data, or in simulation. New version (2.0).
