Claim 0:
1. A crosstalk analysis method for qubits, performed by a terminal, the method comprising:
determining a first qubit and a second qubit that are to be analyzed;
sequentially performing spectral quantum process tomography on quantum states respectively 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;
synchronously performing spectral quantum process tomography on the quantum states respectively 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.
