Stark-Rescue Qubit Reclamation Service

A software calibration layer that detects superconducting qubits degraded by two-level-system (TLS) material defects and shifts their frequency with off-resonant AC Stark drives to restore usable coherence, with zero hardware changes. Independent experiments now corroborate the mechanism — dressed qubits keep standard control, and Stark tones can be managed addressably at scale — but TLS frequencies measurably drift over time and strong drives can induce spurious off-resonant transitions, so the service is designed as a bounded-power, closed-loop scan-and-rescue cycle rather than a one-time fix.
