Operation of HTS Digital Circuits at Elevated Temperatures: Beating Thermal Activation
Abstract
Recent fabrication of High-Tc (HTS) Josephson junctions (JJs) with ion-beam damagedbarriers by Cybart at UCSD create opportunities to employ these junctions in superconducting circuits at temperatures up to 77 K. In this project, the PI will investigate how well these junctions perform in analog and digital circuits up to 77 K, measuring properties at different temperatures over a wide frequency range and develop a frequency and temperature-dependent theoretical model. Special attention will be given to thermal activation, which limits the operational margins at elevated temperatures for superconducting digital circuits.
