Physics Colloquium

Feedback control is ubiquitous in contemporary technology, broadly incorporated within analog and digital system architectures to ensure robust performance and to synthesize network dynamics.  Given the sensitivity of quantum systems to perturbations, the accuracy demands of quantum applications, and fundamental questions surrounding the complexities of quantum synthesis, should we be doing more to develop concepts and methods in quantum feedback control?  In this colloquium I will begin with a tutorial overview of principles and applications of feedback control in quantum systems, distinguishing between measurement-based and coherent feedback paradigms.  I will then turn to describe nascent explorations of coherent feedback in the setting of mesoscopic quantum nonlinear optics, focusing on design motifs for photonic physics-based optimization.
