Continuously Monitored Quantum Systems: Inference and Control
April 16th, 2019 JAN KOLODYNSKI Centre of New Technologies
(CeNT), University of Warsaw

The aim of the four lectures is to cover sufficient theory of continuously monitored quantum systems, so that the attendee can afterwards understand and solve simple quantum inference problems involving continuous-time measurement and feedback. For this to be possible, stochastic approach to quantum system dynamics and measurements will be discussed, as well as necessary quantum statistical inference and spectral analysis techniques. The goal is to close with a concrete application: an analysis of recent phase-tracking experiments in optical interferometry. These constitute an example of quantum waveform estimation task with squeezing of light performed in real-time by active feedback and homodyne detection.
