Robust $H_\infty$ Estimation of Uncertain Linear Quantum Systems

Systems and Control 2017-04-12 v3 Optimization and Control Quantum Physics

Abstract

We consider classical estimators for a class of physically realizable linear quantum systems. Optimal estimation using a complex Kalman filter for this problem has been previously explored. Here, we study robust HH_\infty estimation for uncertain linear quantum systems. The estimation problem is solved by converting it to a suitably scaled HH_\infty control problem. The solution is obtained in the form of two algebraic Riccati equations. Relevant examples involving dynamic squeezers are presented to illustrate the efficacy of our method.
