Progress and prospects of superconductor electronics

Abstract

A brief review of the recent progress of superconductor electronics is presented. Special emphasis is made on the 'intrinsic' development of the field, including rapid progress of the low-Tc Josephson junction technology and recent invention of several important devices. In the near future, these developments promise the advent of several outstanding electronic devices which would be of practical value, despite the need for helium cooling. Against this background, introduction of the high-Tc superconductors in the foreseeable future will probably be restricted to the few simplest electronic devices and components.
