PURPOSE:To simultaneously switch Josephson elements, by a method wherein the Josephson elements are placed at an upper and a lower part with super conductive control line inbetween, and the line is charged with a gate current. CONSTITUTION:Josephson elements 2a and 2b are placed at an upper and a lower part, respectively, of a gate electrode of a lead super-conductive control line 1 charged with a gate current. The element 2a, positioned at the upper part of the line 1, is made of a super-conductive metal such as pb nipping an oxidized film layer 3 of a super-conductor, such as Pbo, having a thickness of, for example, 10Angstrom -50Angstrom , and a switching line, wherein a bias current flows, is placed. The structure of the element 2b is the same as that of the element 2a, and a gate current, flowing to the line 11 by means of the elements 2a and 2b, forms a magnetic field. The gate current is caused to flow to the line 11, and this permits simultaneous switching of the elements 2a and 2b. |
