Abstract

This award allows Roman Sobolewski to collaborate with Michael Siegel of the National Research Center (Forschungszentrum) in Juelich, Germany. The project will investigate the intrinsic dynamical properties of high-temperature superconducting Josephson junctions by experimental determination of the coupling mechanism for the junction when switched either by picosecond electrical pulses or perturbed by femtosecond-pulse optical excitations. The ultimate goal of the research is to develop and fabricate high-temperature superconducting devices and circuits for ultrafast computing and optoelectronic links for supercomputing electronics. The research will also test the ultimate limit of the operating speed of a single-flux quantum superconducting Josephson gate.
