Abstract
This application discloses a quantum gate optimization method performed by a computer device. The method includes: obtaining an initialized control external field corresponding to a quantum gate; applying the control external field to a quantum bit (qubit) corresponding to the quantum gate, and acquiring actual measurement data of the quantum gate, the actual measurement data being used for reflecting an actual characteristic of the quantum gate; calculating a gradient corresponding to the control external field based on the actual measurement data and ideal data, the ideal data being used for reflecting an ideal characteristic of the quantum gate; and updating the control external field according to the gradient to obtain an updated control external field, the updated control external field being applied to the qubit corresponding to the quantum gate to optimize precision of the quantum gate. The method is a closed-loop optimization solution driven and implemented by data feedback.
