Abstract
A vertical transmon qubit structure, includes a substrate having a first surface and a second surface. A through-silicon-via (TSV) is located in the substrate. A first electrode of a Josephson junction (JJ) is located on a portion of the first surface of the substrate and adjacent to the TSV. A second electrode of the JJ is in contact with the TSV and on a second portion of the first surface of the substrate. The first electrode is separated from the second electrode by an insulator.
