A superconducting printed circuit board, comprising a first electrically insulative substrate layer having a first surface and a second surface opposed to the first surface, at least a second electrically insulative substrate layer having a first surface and a second surface opposed to the first surface, the second electrically insulative substrate layer physically coupled to the first electrically insulative substrate layer, a first superconducting current path positioned on a first surface side of the first electrically insulative substrate layer, a second superconducting current path positioned between the first and second electrically insulative layer, and a third superconducting current path that extends through the first electrically insulative substrate layer and superconducting couples the first superconducting current path with the second superconducting current path.
