Single solid-state quantum emitters have demonstrated considerable potential for the implementation of important quantum photonic devices such as on-demand single-photon sources or deterministic quantum logic gates. Converting a bare quantum emitter into a device with sufficient performance for use in quantum photonic systems requires an efficient, high cooperativity interface to accessing optical fields. Such interfaces may in principle be implemented through nanophotonic geometries that leverage cavity quantum electrodynamics effects with strongly confined optical modes. A number of critical factors, however, such as preservation of the emitter coherence post-fabrication, and fabrication yield and scalability, must be simultaneously addressed, imposing significant challenges to device development. In this talk I will describe our past and current efforts to target such requirements through nanophotonic design, towards the development of scaled chip-integrated quantum photonic systems with functionality enabled by quantum emitters.
