Abstract

A reciprocal quantum logic (RQL) gate circuit has a first stage having four logical inputs asserted based on receiving positive single flux quantum (SFQ) pulses and storing the SFQ pulses in respective storage loops each associated with a logical input, and a second stage having two more storage loops. First and second logical decision Josephson junctions (JJs) make determinations based on signals stored in the first-stage storage loops. A third logical decision JJ makes a third determination based on the first and second determinations. Each logical decision JJ triggers based on biasing provided by one or more currents stored in its associated storage loops and a bias signal having an AC component. The second stage asserts an output based on the triggering of the third logical decision JJ. Four-input AND, OR, AO22, and OA22 gates are thereby provided.
