Detection of Athermal Quasiparticles using a Josephson Array Microwave Kinetic Inductance Detector (JAMKID)

ORAL

Abstract

Cooper pair breaking in superconducting devices is a widely used detection method for observational astronomy, nuclear science, and X-ray imaging. We have developed a variant of these detectors called a Josephson array microwave kinetic inductance detector (JAMKID). The JAMKID is a small (0.1 mm x 0.02 mm) resonant circuit with a series array of Josephson junctions having electrical impedance that is sensitive to quasiparticle excitations in its constituent thin film aluminum. By virtue of their construction, spatial extent, and method of readout, JAMKID circuits have potential applications as co-located sensors with superconducting quantum circuit devices. In this talk we discuss the feasibility of JAMKIDs for reliable detection of ionizing radiation impacts and how these devices might inform error mitigation in superconducting quantum processors.
