A Direct Coupling Coherent Quantum Observer for a Single Qubit Finite Level Quantum System (1409.2594v1)
Published 9 Sep 2014 in quant-ph, cs.SY, and math.OC
Abstract: This paper considers the problem of constructing a direct coupling quantum observer for a single qubit finite level quantum system plant. The proposed observer is a single mode linear quantum system which is shown to be able to estimate one of the plant variables in a time averaged sense. A numerical example and simulations are included to illustrate the properties of the observer.
