Abstract:
A single-flux-quantum digital device comprising:a first superconducting line extended in a larger ring; a second superconducting line connected to the first superconducting line so as to divide the large ring of the first superconducting line into two small rings; a switching device that regulates a supercurrent flowing through the second superconducting line; and a detecting device that detects a change in the supercurrent flowing through the first superconducting line, wherein the two small rings are substantially the same in shape and area; the detecting device is connected to a joint where the first superconducting line and the second superconducting line are joined; and the first superconducting line and the second superconducting line are smaller in width so that magnetic flux induced by the supercurrent circularly flowing along the first superconducting line and the second superconducting line is negligible.
