In-situ tunable superconducting diode: towards field-free operation with infinite nonreciprocity
Razmik A. Hovhannisyan, Taras Golod, Amirreza Lotfian +1
Efficient, scalable, and magnetic-field-free superconducting diodes are essential for future superconducting electronics; yet, despite significant efforts, such practical devices r…
Demonstration of an optical microwave rectification by a superconducting diode with near 100% efficiency
Razmik A. Hovhannisyan, Amirreza Lotfian, Taras Golod +1
Superconducting electronics offer significant advantages in speed and power efficiency for next-generation computing and communication systems. However, their practical deployment…
Resonant switching current detector based on underdamped Josephson junctions
Vladimir M. Krasnov
Current-biased Josephson junctions can act as detectors of electromagnetic radiation. At optimal conditions, their sensitivity is limited by fluctuations causing stochastic switchi…
Cascade switching current detectors based on arrays of Josephson junctions
Roger Cattaneo, Artemii E. Efimov, Kirill I. Shiianov +2
Cascade multiplication is a common technique to enhance the sensitivity of photon detectors. In this study, we demonstrate novel cascade-amplified superconducting detectors utilizi…
