Digital logic circuits
Description
Recent progress in Josephson digital logic circuits is described. Changing of the junction material from a lead alloy to niobium has dramatically improved process reliability, and high-speed, low-power operations have been demonstrated at large-scale integrated-circuit levels. The first Josephson microprocessor, operated at 770 MHz, verified the potential of Josephson devices for future digital elements. The possibilities of the ultrafast Josephson computer, previously shelved by a number of problems, are now being actively reconsidered. The performance anticipated for Josephson digital circuits using high-temperature superconducting materials is also discussed
