Colloquium: Hybrid Superconducting Photonic Circuits

Speaker: Hong Tang, Yale University

Abstract: Superconducting and photonic circuits are among the most advanced platforms for quantum information processing. However, superconductivity and optics are incompatible in many aspects as superconductors could absorb photons and optical excitations are known to lead to excess microwave noises. I will present an ongoing effort at Yale that brings superconductivity and optics on a single chip platform, which enables new functions including ultrasensitive photon-number resolved detectors, efficient microwave-to-optical converters for quantum networks, and superconducting electro-optic modulators for cryogenic data links.
