A numerical approach to optimal coherent quantum LQG controller design using gradient descent

Sichani (Khodaparastsichani), Arash Kh.; Vladimirov, Igor; Petersen, Ian


This paper is concerned with coherent quantum linear quadratic Gaussian (CQLQG) control. The problem is to find a stabilizing measurement-free quantum controller for a quantum plant so as to minimize a mean square cost for the fully quantum closed-loop system. The plant and controller are open quantum systems interconnected through bosonic quantum fields. In comparison with the observation–actuation structure of classical controllers, coherent quantum feedback is less invasive to the quantum...[Show more]
