JOSEPHSON JUNCTION WITH SPACER |
| 摘要 |
Various embodiments are directed toward a circuit configured to act as a Josephson junction. The circuit may comprise: a junction stack on a substrate, the junction stack including a portion of a first superconductor electrode, with an interface layer on a top side of the first superconductor electrode and configured to act as a tunneling barrier for the junction stack. The circuit may also comprise a first portion of a second superconductor electrode on top of the interface layer. A spacer may separate the portion of the first superconductor electrode in the junction stack from a second portion of the second superconductor electrode outside the junction stack where the second superconductor electrode overlays the first superconductor electrode. |

1. A circuit configured to act as a Josephson junction, comprising:
a junction stack on a substrate, the junction stack including:
a portion of a first superconductor electrode;an interface layer on a top side of the first superconductor electrode and configured to act as a tunneling barrier for the junction stack;a first portion of a second superconductor electrode on top of the interface layer; and a spacer separating the portion of the first superconductor electrode and from a second portion of the second superconductor electrode that is outside the junction stack. |
