Abstract: The present disclosure provides a two-dimensional scalable superconducting qubit structure and a method for controlling a cavity mode thereof. The two-dimensional scalable superconducting qubit structure includes: a superconducting qubit chip comprising a plurality of two-dimensionally distributed and scalable qubits; a capacitor part of each of the qubits has at least five arms distributed two-dimensionally, two of the at least five arms in each qubit are respectively connected with a read coupling circuit and a control circuit, and the other at least three arms are coupled with adjacent qubits through a coupling cavity.
