The pioneers of superconducting electronics are accumulating an impressive record of achievement. For example, they have now gained the high‐performance lead in the important field of digital electronics. Logic delays of 13 picoseconds and switching times of 9 picoseconds have been experimentally demonstrated. The same basic devices, Josephson junctions, also make the most sensitive microwave detectors, the most sensitive magnetometers (or current sensors) and the most stable voltage sources. Although each of these developments is an important independent accomplishment, the combination of these developments in a single technology merits special attention.
