Abstract

Recent development in chip-based photonic quantum circuits has radically impacted the ways in which we can process quantum information. However, it is challenging for any one specific integrated photonics platform to meet the stringent demands for most quantum applications. Hybrid platforms that combine different photonic materials in a single functional unit have great potential to overcome the limitations of current photonic circuits. This idea is now being transferred to quantum technology. In this review, we summarize the state-of-the-art of quantum technologies that can be implemented in a hybrid photonic circuit platform. We discuss the technical considerations in building such a platform, introduce first successful realizations, and address the remaining outstanding requirements for future practical applications.
