Abstract
A superconducting circuit having a Josephson junction includes 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 a 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 includes a non-aluminum superconducting material to prolong a coherence time of superconducting qubits.
