Scalable photonic quantum information processors require methods to integrate single photon sources with compact photonic devices that can manipulate the quantum light on-a-chip. Simple monolithic integration of quantum emitters and photonic structures such as waveguides and beam splitters has shown possible potentials of on-chip quantum photonic devices. However, as the complexity of the quantum system grows fast, integrating multiple quantum emitters with more functional and integrated photonic components are becoming more important. Hybrid integration allows us to perform post selection of the quantum emitters and to employ advanced photonic circuits such as Si photonic chips for these emitters. Therefore, such integration could enable complex quantum information processors in a compact solid-state material. Here, we will present the recent progress on the hybrid integration of solid-state quantum emitters with various dissimilar platforms. This integration opens up the possibility to leverage the highly-advanced photonic capabilities developed in photonic chips to control and route non-classical light from on-demand single photon sources. Also, we will discuss the quantum emitters at telecom wavelengths and their integration with fiber platforms, which are useful for fiber-based quantum communication. Our technique could solve one of the main challenges for a scalable quantum system.
