Quantum Rabi Ramsey Analysis

by Rabi/Ramsey trace analysis in Search & web

x402 APIPassing, checked 2 h ago

Fit a bounded damped Rabi/Ramsey trace by frequency-decay grid search; report residuals, resolution, aliasing refusal and edge hits. No parameter confidence interval. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.
