Abstract: A superconducting qubit coupling structure and a superconducting quantum chip are provided, related to the field of quantum computation technology, in particular to the field of superconducting quantum chip technology. The superconducting qubit coupling structure includes two superconducting qubit units, wherein each superconducting qubit unit includes a first metal electrode plate and four second metal electrode plates, the first metal electrode plate is X-shaped and forms openings in four directions; the four second metal electrode plates are located in the openings respectively, and form coupling ports for coupling to a qubit that have the same structural dimension. Coupling ports located in opposing openings of two superconducting qubit units respectively are connected to form a capacitor layout structure of a coupler, and a distance between geometric centers of the first metal electrode plates of two superconducting qubit units is within a range bounded by 385 m a first preset value.
