Derives motional frequencies, classical trajectories, and a quantum master equation for nanoparticle-ion systems, predicting sympathetic cooling to sub-kelvin temperatures with linear scaling for multiple ions.
The likelihood ratio test on full position probability distributions certifies macroscopic quantum mechanics with an exponential reduction in required measurements compared to visibility-based methods.
