  The emergence of coherent quantum feedback control (CQFC) as a new paradigm
for precise manipulation of dynamics of complex quantum systems has led to the
development of efficient theoretical modeling and simulation tools and opened
avenues for new practical implementations. This work explores the applicability
of the integrated silicon photonics platform for implementing scalable CQFC
networks. If proven successful, on-chip implementations of these networks would
provide scalable and efficient nanophotonic components for autonomous quantum
information processing devices and ultra-low-power optical processing systems
at telecommunications wavelengths. We analyze the strengths of the silicon
photonics platform for CQFC applications and identify the key challenges to
both the theoretical formalism and experimental implementations. In particular,
we determine specific extensions to the theoretical CQFC framework (which was
originally developed with bulk-optics implementations in mind), required to
make it fully applicable to modeling of linear and nonlinear integrated optics
networks. We also report the results of a preliminary experiment that studied
the performance of an in situ controllable silicon nanophotonic network of two
coupled cavities and analyze the properties of this device using the CQFC
formalism.
