Claim 16:
17. 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;
performing spectral quantum process tomography on a quantum state of the first qubit, and parsing a signal function that corresponds to the first qubit and is obtained through tomography, to obtain a first eigenspectrum, the second qubit being in a waiting state when spectral quantum process tomography is performed on the quantum state of the first qubit;
performing spectral quantum process tomography on a quantum state of the second qubit, and parsing a signal function that corresponds to the second qubit and is obtained through tomography, to obtain a second eigenspectrum, the first qubit being in a processing state based on target gating when spectral quantum process tomography is performed on the quantum state of the second qubit; and
determining a transmission line crosstalk intensity between the first qubit and the second qubit according to the first eigenspectrum and the second eigenspectrum.
