Abstract
A quantum interference device comprises a superconducting loop interrupted by a gap; a plurality of normal conductor segments bridging the gap; and an interferometer connected to the normal conductor segments, wherein the normal conductor segments are spaced apart. There may be 2N+1 normal conductor segments, where N is a positive integer, which may be of equal length and evenly spaced. The device produces a larger signal than a conventional quantum interference device.
