Claim:
A superconducting inductor ladder circuit comprising: a first closed superconducting current path that includes at least two superconducting inductors coupled in series with each other along the first closed superconducting current path to form a first superconducting loop; at least a second closed superconducting current path that includes at least two superconducting inductors coupled in series with each other along the second closed superconducting current path to form a second superconducting loop, wherein the first and the second superconducting loops are connected in parallel with each other such that there is a portion of the first and the second closed superconducting current paths that includes at least one of the superconducting inductors that is shared by the first and the second superconducting loops, and at least one of the superconducting inductors of the first superconducting loop is not shared with the second superconducting loop and at least one of the superconducting inductors of the second superconducting loop is not shared with the first superconducting loop; a data signal input structure configured to couple data signals to at least one of the unshared superconducting inductors in each of at least the first and the second superconducting loops; and a data signal output structure configured to couple data signals from at least one of the first and the second superconducting loops.
