Abstract
Disclosed is a superconducting device comprising a logic SQUID and a readout SQUID magnetically coupled with the logic SQUID, which are fabricated using a single layer of an oxide high-temperature superconductor, wherein the logic SQUID comprising a superconducting loop constituted by a first superconducting line, a second superconducting line arranged to be parallel to the first superconducting line, third and fourth superconducting lines provided to connect the first and second superconducting lines, and two Josephson junctions formed in the third and fourth superconducting lines, and widths W.sub.1 and W.sub.2 of the first and second superconducting lines are larger than a distance d between them, the width W.sub.2 is larger than the width W.sub.1, and the widths W.sub.1 and W.sub.2 are larger than the widths W.sub.3 and W.sub.4 of the third and fourth superconducting lines.
