Title:
OPTICAL APPARATUS, SYSTEM, AND METHOD FOR QUANTUM COMPUTING, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/071648
Kind Code:
A1
Abstract:
The present application relates to the technical field of quantum computing, and discloses an optical apparatus, system, and method for quantum computing, and a storage medium. The apparatus comprises: a delay generation module (10), used for generating different time delays respectively for n photons so that the n photons arrive at an active optical element at different time points, respectively; a fiber collimation module (20), used for converting light of the n photons into n paths of collimated light for propagation; a quasi-spatial mode generation module (30), used for enabling the light of the n photons to sequentially pass through the same active optical element, the active optical element being used for sequentially modulating optical signals of the n photons according to the sequence of times of arrival of the n photons; and a feedforward measurement module (40), used for performing polarization measurement on the modulated optical signal of a first photon and obtaining a measurement result, the result being used for performing feedforward compensation or feedforward error correction on a measurement result for a second photon to be measured.
