Picosecond Josephson samplers: Modeling and measurements

June 4, 2025
Author(s)
Logan Howe, Bart van Zeghbroeck, David Olaya, John Biesecker, Charles Burroughs, Peter Hopkins, Samuel Benz
Measurement of signals generated by superconducting Josephson junction (JJ) circuits require ultra-fast components located in close proximity to the generating circuitry. We report a detailed study of optimal design criteria for a JJ-based sampler that
