Title:
量子ゲートの最適化方法、装置、機器、記憶媒体及びコンピュータプログラム
Document Type and Number:
Japanese Patent JP7371234
Kind Code:
B2
Abstract:
A method and an apparatus for optimizing a quantum gate, a device, and a storage medium are provided. The method includes: obtaining an initialized control external field corresponding to a quantum gate; applying the control external field to a quantum bit of 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 of the control external field based on the actual measurement data and ideal data; 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 quantum bit of the quantum gate to optimize precision of the quantum gate. The quantum gate optimization solution provided above is a closed-loop optimization solution driven and implemented by data feedback. An optimization algorithm based on gradient constraint is combined with actual measurement data, thereby providing a quantum gate optimization solution that improves both the precision and efficiency.
