- a substrate;
a patterned layer of superconducting material disposed over the substrate, the patterned layer forming;
a first electrode;
a second electrode; and
a loop coupling the first electrode with the second electrode by a first channel and a second channel, wherein the first channel has a first minimum width and the second channel has a second minimum width that is distinct from the first minimum width;
a magnet configured to apply a magnetic field to the loop in the patterned layer of superconducting material, wherein the magnetic field produces an expulsion current in the loop that travels toward the second electrode in the first channel and toward the first electrode in the second channel;

Abstract
An electronic device (e.g., a diode) is provided that includes a substrate and a patterned layer of superconducting material disposed over the substrate. The patterned layer forms a first electrode, a second electrode, and a loop coupling the first electrode with the second electrode by a first channel and a second channel. The first channel and the second channel have different minimum widths. The device further includes a magnet that applies a magnetic field to the loop, which produces an expulsion current in the loop that travels toward the second electrode in the first channel and toward the first electrode in the second channel. For a range of current magnitudes, when the magnetic field is applied to the patterned layer of superconducting material, the conductance from the first electrode to the second electrode is greater than the conductance from the second electrode to the first electrode.
