Robust smoothing for estimating optical phase varying as a continuous resonant process

Roy, Shibdas; Rehman, Obaid; Petersen, Ian R; Huntington, Elanor Harriet


Continuous phase estimation is known to be superior in accuracy as compared to static estimation. The estimation process is, however, desired to be made robust to uncertainties in the underlying parameters. Here, homodyne phase estimation of coherent and squeezed states of light, evolving continuously under the influence of a second-order resonant noise process, are made robust to parameter uncertainties using a robust fixed-interval smoother, designed for uncertain systems satisfying a certain...[Show more]
