Single quantum emitters are an important resource for quantum photonics, constituting building blocks for single-photon sources, qubits, and deterministic quantum gates. Robust implementation of such functions, however, can only be achieved through systems that provide both strong light–matter interactions and a low-loss interface between emitter and probing optical fields. We developed a heterogeneous photonic integration platform that provides such features in a scalable on-chip implementation that allows direct integration of GaAs nanophotonic devices containing self-assembled InAs/GaAs quantum dots within passive photonic circuits composed of low-loss Si3N4 waveguides.
