An asymmetrical interferometer having two Josephson junctions with unequal contact areas. In accordance with the invention, the magnetic flux magnitudes of the control lines of the Josephson junctions are approximately equal in each Josephson junction. In a preferred embodiment, the length of the Josephson junctions along a direction parallel to the control line are equal to each other. Moreover, each Josephson junction is provided with a counterelectrode metalization, the counterelectrode metalizations having substantially equal widths measured in a direction orthogonal to the control line. The widths of the counterelectrode metalizations are larger than the width of an inductive connection between the Josephson junctions.
