Optical photons are natural carriers of quantum information and have led to numerous breakthroughs in quantum communication, networking, sensing, and computation. Despite impressive proof-of-concept demonstrations, implementing practical quantum algorithms requires a new level of complexity, where thousands to millions of optical elements need to be put together. Integrated photonics is likely the only solution.

Our group aims to develop an integrated photonic platform for scalable quantum information, allowing single-photon generation, control, and detection on a single integrated chip. We rely on two key technologies — thin-film lithium niobate photonics and superconducting nanowires. The combination of the two will enable novel functionalities and applications such as microwave-optical transduction, single-photon feedforward, as well as advanced multiplexing and encoding schemes for photonic qubits. Our expertise is in nanofabrication, integrated photonics, and applied superconductivity. Beyond integrated quantum photonics, our research extends broadly to nanoplasmonics, superconducting microwave circuits, and classical optoelectronics devices.
