Josephson nonlatching logic circuits

The authors describe nonlatching logic circuits that can be designed using Josephson junctions as the switching elements. The circuits require no current resetting and can be switched between their two logic states with a subnanosecond delay time. The switching behavior has been simulated numerically. The choice of parameters and junction types is analyzed. The distinctive features which make these circuits attractive are discussed.
