  This chapter covers recent developments in the field of hybrid quantum
photonics based on color centers in nanodiamonds and Si3N4-photonics towards a
technology platform with applications in quantum information processing and
quantum information distribution. The methodological approach can be divided in
three main tasks. First, the fabrication and optimization of Si3N4-photonics.
Second, the creation, characterization and control of color centers in
nanodiamonds. Third, the assembly of hybrid quantum photonics by integrating
the nanodiamonds into the photonic structures. One focus will be the efficient
interfacing of the color centers done by optimizing the optical coupling. The
chapter describes recent progress in all three steps and summarizes the
established hybrid platform. We believe, that the hybrid approach provides a
promising path to realize quantum photonic applications, such as quantum
networks or quantum repeaters, in the near future.
