Characteristics of a counter-electrode coupled logic gate using Josephson junctions

This paper proposes a new superconducting logic device controlled by input signal currents applied to the counter-electrode of a tunneling junction. This device has no specific control lines unlike the conventional magnetically coupled logic devices. Input signals couple to the junction magnetically by using the counter-electrode instead of the control line. We call this a Counter-electrode Coupled Logic (CCL) gate. The following describes the basic characteristics of the CCL gate.
