Classification: CPC G | IPC G

Claim 8:
9. A crosstalk analysis apparatus for qubits, comprising a memory storing computer instructions and a processor coupled to the memory, when executing the computer instructions, the processor being configured to:
identify a first qubit and a second qubit;
sequentially perform 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;
synchronously perform 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
determine a crosstalk intensity between the first qubit and the second qubit based on the first eigenspectrum, the second eigenspectrum, and the third eigenspectrum.
