Abstract
This application relates to a method for analyzing crosstalk between qubits, performed by a terminal. The method includes identifying a first qubit and a second qubit; performing spectral quantum process tomography on quantum states corresponding to the first qubit and the second qubit, to obtain a first eigenspectrum of a signal function corresponding to the first qubit and a second eigenspectrum of a signal function corresponding to the second qubit; performing spectral quantum process tomography on the quantum states corresponding to the first qubit and the second qubit, to obtain a third eigenspectrum of a common signal function of the first qubit and the second qubit; and determining a crosstalk intensity between the first qubit and the second qubit based on the first eigenspectrum, the second eigenspectrum, and the third eigenspectrum.
