Synthesis of generalized linear quantum stochastic systems via quantum feedback networks

The aim of this paper is to contribute to a new synthesis algorithm for generalized linear quantum stochastic systems that are usually encountered in linear quantum optics and in phenomenological models of linear quantum circuits. In particular, such a theory will enable the systematic realization of generalized coherent quantum linear stochastic controllers for quantum control. We show how an any generalized linear quantum stochastic system can be synthesized in a systematic way from one degree of freedom generalized open quantum harmonic oscillators.
