Interfacing solid-state quantum emitters into real-world photonic platforms

Solid-state quantum emitters have attracted much attention as integrated sources of photonic and spin qubits, which are basic elements for a range of quantum applications. Recent advances in the generation, manipulation, and integration of these emitters demonstrate a variety of quantum resources: bright quantum light sources, quantum memories, and spin-photon interfaces. In particular, integrating quantum emitters with photonic cavities or waveguides enables scalable quantum interactions between multiple photons and emitters. Given their high performance and scalability, quantum emitters are taking the next stages towards scalable, integrated quantum systems on photonic integrated circuits or fiber optics. Therefore, all quantum operations are efficiently possible in real-world photonic platforms. To achieve this goal, several technologies, including high-efficiency photonic interfaces, precise hybrid integration, and local frequency control, must be implemented in a practical photonic platform. In this talk, I present recent races and future challenges in scalable, integrated quantum photonics.
