Abstract
The present disclosure discloses a method and apparatus for optimizing a qubit control signal, and a quantum computer. The method includes: 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, where 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 optimizing the qubit control signal based on the detuning amount of the frequency.
