Abstract

A discussion is presented of one of the simplest models of Josephson computer systems (phase mode system), in which quantized vortices of magnetic flux (fluxoids) are employed as information bits and in which all logic functions are achieved by interactions between fluxoids. In a phase mode system, device operation depends on the existence of many stable states differing from each other by integer multiples of 2π in the phase plane. As an example, the authors propose a simple model of a complete phase mode computing system and discuss the basic computer elements and the instruction in this system. The total system is considered to be a prototype of quantum computer systems in which physical quantum states are employed as logic states for information processing.
