Room temperature integrated light-squeezing single-photon detectors for quantum systems

The project explores nonlinear integrated devices as potential room-temperature single-photon and photon-number-resolving detectors for quantum computing and communication. It focuses on performance limitations of integrated squeezing optical parametric amplifiers (OPAs) based on thin-film ferroelectric materials like lithium niobate. Key aspects investigated include detection efficiency, dark count rate, and integration feasibility with modern quantum technologies. Success in this area could reduce reliance on cryogenic hardware, advancing scalable quantum applications.
