Claim 17:
18. A device comprising a superconducting circuit, the superconducting circuit comprising a Josephson junction, and the Josephson junction comprising:
a preset substrate;
a first electrode layer for signal transmission;
a second electrode layer for signal transmission; and
an insulating layer arranged between the first electrode layer and the second electrode layer to form the Josephson junction,
wherein, the first electrode layer and the second electrode layer are composed of a preset material, the insulating layer is composed of a compound corresponding to the preset material, and the preset material comprises a non-aluminum superconducting material, and
wherein the first electrode layer is disposed on the preset substrate, the insulating layer is disposed on the first electrode layer, and the second electrode layer is a continuous bridge structure comprising:
a first end disposed on the insulating layer,
a second end arranged disposed on the preset substrate, and
a middle sub-electrode between the first and send ends, the middle sub-electrode being disposed over and forming an air gap from the preset substrate.
