Abstract

The invention discloses a quantum gate optimization method and device, equipment and a storage medium, and relates to the technical field of quantum. The method comprises the following steps: acquiring an initialized control external field corresponding to a quantum gate; applying a control external field to quantum bits corresponding to the quantum gate, collecting actual measurement data of the quantum gate, wherein the actual measurement data are used for reflecting actual characteristics of the quantum gate; calculating a gradient corresponding to the control external field based on the actual measurement data and the ideal data; updating the control external field according to the gradient, wherein the updated control external field is used for being applied to a quantum bit corresponding to the quantum gate so as to optimize the precision of the quantum gate. The quantum gate optimization scheme provided by the invention is a closed-loop optimization scheme realized by utilizing data feedback driving, and the quantum gate optimization scheme considering both precision and efficiency is realized by combining an optimization algorithm with gradient constraint with actual measurement data.
