Ultra-high-speed Operation of Josephson Tunneling Devices

by H. H. Zappe, K. R. Grebe
Switching times of large Josephson devices have been measured. We report gate switching times of 85 ps and array cycle times of an elementary memory cell of 550 ps. Although these times are expected to be smaller in more realistic miniaturized devices, they represent to our knowledge, the shortest times for such circuits ever reported in any technology.
