Abstract
Superconducting digital logic circuits constructed in accordance with this invention include a circuit branch having first and second Josephson junctions electrically connected in series with each other, with a junction point between the first and second Josephson junctions connected to a neutral point; a positive bias voltage is connected to one end of the circuit branch, and a negative bias voltage is connected to a second end of the circuit branch; a first rail for applying a first input voltage signal, having a first polarity, and for extracting a first output signal is connected to one end of the circuit branch; and a second rail for applying a second input voltage signal, having a second polarity, and for extracting a second output signal is connected to the other end of the circuit branch. This invention encompasses both the above circuit and the method of signal processing performed by such circuits.
