1. A device comprising:
a substrate;
a first superconductor layer on a top surface of the substrate;
an insulator layer on a top surface of the first superconductor layer;
a second superconductor layer on a top surface of the insulator layer, wherein the first superconductor layer, the insulator layer, and the second superconductor layer form a Josephson junction; and
a third superconductor layer, wherein a first portion of the third superconductor layer is directly in contact with a top surface of the first superconductor layer and extends along a first direction to provide a first contact to the Josephson junction, and a second portion of the third superconductor layer is directly in contact with a top surface of the second superconductor layer and extends along a second direction to provide a separate second contact to the Josephson junction,
wherein an edge of the first contact is separate and laterally spaced apart from an edge of the second contact along the first direction,
wherein the first superconductor layer comprises a first portion that forms a bottom electrode to the Josephson junction, and
wherein the second superconductor layer comprises a first portion that forms a top electrode to the Josephson junction.
