Abstract:
1. A superconducting integrated circuit comprising: a first superconducting current path disposed in a first metal layer; a first dielectric layer, at least a portion of which is carried on the first metal layer; a second superconducting current path disposed in a second metal layer that is carried on the first dielectric layer, wherein at least a portion of the second superconducting current path overlies at least a portion of the first superconducting current path; a second dielectric layer, at least a portion of which is carried on the second metal layer; a third superconducting current path disposed in a third metal layer that is carried on the second dielectric layer, wherein at least a portion of the third superconducting current path overlies at least a portion of both the first and second superconducting current paths; a first superconducting connection between the first superconducting current path and the third superconducting current path, wherein the first superconducting connection extends through both the first dielectric layer and the second dielectric layer; and a second superconducting connection between the first superconducting current path and the third superconducting current path, wherein the second superconducting connection extends through both the first dielectric layer and the second dielectric layer, and wherein at least a portion of the second superconducting current path is encircled by an outer superconducting current path formed by at least a portion of the first superconducting current path, at least a portion of the second superconducting current path, and the first and second superconducting connections, and wherein the second superconducting current path is the third superconducting current path is communicatively coupleable to the closed superconducting loop via an inductive coupling.
