Abstract
A superconducting threshold logic circuit comprises current switching circuits each having a Josephson device. Bias currents of the switching circuits are varied independently to change weights for input signals. A sum of the weighted input signals are inputted to another current switching circuit having a Josephson device in order to compare the sum with a threshold.
