Time Averaged Consensus in a Direct Coupled Coherent Quantum Observer Network for a Single Qubit Finite Level Quantum System (1503.01179v1)

Abstract: This paper considers the problem of constructing a direct coupled quantum observer network for a single qubit quantum system. The proposed observer consists of a network of quantum harmonic oscillators and it is shown that the observer network output converges to a consensus in a time averaged sense in which each component of the observer estimates a specified output of the quantum plant. An example and simulations are included.
