1. A method for optimizing a qubit control signal, comprising:
obtaining an operating frequency of a qubit based on a Ramsey experiment;
obtaining a detuning amount of a frequency of the qubit control signal based on an amplified phase error (APE) experiment, wherein the APE experiment is an experiment that measures a change in quantum state information of the qubit with a preset detuning amount of the frequency of the qubit control signal, and the frequency of the qubit control signal is set according to the operating frequency of the qubit; and
determining the qubit control signal based on the detuning amount of the frequency.
