Abstract

This paper is concerned with the state space modelling of closed optical QED feedback control system in interacting Fock space which is shown to be a generalization of Langevin stochastic model in boson Fock space. This work includes the design of quantum networks of the feedback systems of QED cavity using two-mode beam splitter device at the input to the cavity and a single mode fractional beam splitter device at the output of the cavity in interacting mode and their stability analysis using Nyquist criterion.
