ABSTRACT:
A superconducting junction device which is easily manufactured, multifunctional, and utilizes the superconducting Josephson effects is described. A first junction (Josephson junction) and a second junction (Josephson junction) are disposed o a substrate across a coupling portion of a dielectric. The first junction comprises a first upper electrode, a first barrier layer and a first lower electrode. The second junction comprises a second upper electrode, a second barrier layer and a second lower electrode. The first lower electrode and the second lower electrode are connected in series via a connecting electrode. A superconducting reflecting wall which is connected via the connecting electrode is provided around the two Josephson junctions including the coupling portion.
