Robustness of system-filter separation for the feedback control of a quantum harmonic oscillator undergoing continuous position measurement

Szigeti, Stuart; Adlong, Sarah; Hush, Michael; Carvalho, Andre; Hope, Joseph

Description

We consider the effects of experimental imperfections on the problem of estimation-based feedback control of a trapped particle undergoing continuous position measurement. These limitations violate the assumption that the estimator (i.e., filter) accurately models the underlying system, thus requiring a separate analysis of the system and filter dynamics. We quantify the parameter regimes for stable cooling and show that the control scheme is robust to detector inefficiency, time delay,...[Show more]
