A Possible Implementation of a Direct Coupling Coherent Quantum Observer

Abstract

This paper considers the problem of implementing a previously proposed direct coupling quantum observer for a closed linear quantum system. This observer is shown to be able to estimate some but not all of the plant variables in a time averaged sense. The paper proposes a possible experimental implementation of the observer plant system using a non-degenerate parametric amplifier.

A reduced version of this paper has been accepted to appear in the 2015 Australian Control Conference. arXiv admin note: text overlap with arXiv:1408.0399
