Abstract: Provided are a method for coupling any two qubits from among multiple superconducting qubits and a system thereof, which are applied to an occasion provided with a multi-superconducting-qubit array and a magnetic film material capable of implementing spin waves. The method includes: disposing a magnetic film material below a multi-superconducting-qubit array; forming, through a combination of magnetization directions of magnetic domains in the magnetic film material, multiple channels through which the spin waves pass; disposing multiple qubits of the multi-superconducting-qubit array above the multiple channels through which the spin waves pass correspondingly to implement a coupling between each qubit and the spin waves; and disposing at least two qubits above one spin wave channel and implementing a coupling between the at least two qubits through the coupling between each qubit and the spin waves.
