PURPOSE:To obtain the titled superconductive circuit device, whose area can be reduced as a whole, by arranging a common grounding superconductor layer between at least two superconductive circuit constitution parts, and laminating them on a substrate. CONSTITUTION:In the constitution comprising the superconductive circuit constitution parts 10A and 10B and the grounding superconductor layer 2AB, a current is flowed through superconductor layers 9a and 9B constituting the superconductive circuits 4A and 4B, by the grounding superconductor 2AB, and a magnetic field is generated around the superconductor layers 9A and 9B. The magnetic field is located between the grounding superconductor layer 2AB and the superconductor layers 9A and 9B. Josephson junctions 11A and 11B constituting the superconductive circuits 4A and 4B are effectively switched and controlled. The grounding superconductor 2AB, which is provided between the superconducting circuit constitution parts 10A and 10B, indicates diamagnetic property. Therefore, the constitution comprising the superconductive circuit constitution part 10A and the grounding superconductor 2AB and the constitution comprising the superconducting circuit constitution part 10B and the grounding superconductor layer 2AB are operated under the magnetically separated state by the grounding superconductive layer 2AB. |
