Abstract
The University of Central Florida invention is a highly sensitive, broadly tunable detector for multi-domain sensing and quantum information systems. With a non-thermal “video” mechanism, the detector offers substantial single-photon sensitivity at high speeds when coupled to a suitable antenna. Josephson junctions in the UCF material feature high dynamic resistance at the maximum zero voltage current. Biased at this current, a small microwave voltage across the junction shifts the voltage-current step, resulting in a large DC output voltage. When driven by external radiation, the antenna can source the desired AC voltage across the junction. Additionally, the bolometric response has a temperature coefficient of resistance estimated at 300 percent/K.
