Quantum information science (QIS) technologies for computing, communications, sensing, and metrology rely on the ability to generate and detect non-classical information using light and matter. Photonics plays a central role in QIS because of the inherent scalability and low-loss, high-speed transmission of light. Yet, despite its ubiquitous presence, there are no high-performance, scalable, turnkey sources of quantum light, such as single photons or entangled-photon pairs. In this talk, I will provide an overview of my research in quantum nanophotonics with an emphasis on materials processing, fabrication, and metrology of chip-scale devices based on III-V semiconductors and 2D materials. I will present examples of how we are answering challenging questions such as: How can we produce and detect single photons on demand with high efficiency? What is the optimal approach for developing a fully integrated, chip-scale platform that combines quantum light sources, photonic circuits, and single-photon detectors? Is it possible to create artificial quantum materials and structures with tunable and programmable properties for QIS? I will also provide an outlook on future directions for achieving new functionality and capabilities in QIS and distributed quantum computing using a hybrid platform combining quantum nanophotonics with other quantum systems, such as acoustic cavities and superconducting circuits.
