Title:
QUANTUM ERROR CORRECTION DECODING SYSTEM AND METHOD, FAULT-TOLERANT QUANTUM ERROR CORRECTION SYSTEM, AND CHIP
Document Type and Number:
WIPO Patent Application WO/2022/166199
Kind Code:
A1
Abstract:
A quantum error correction decoding system and method, a fault-tolerant quantum error correction system, and a chip, relating to the technical field of quanta. The quantum error correction decoding system comprises a plurality of error correction chips. The error correction chips are used for: acquiring error syndrome information of a quantum circuit (131); and operating a neural network decoder to decode the error syndrome information to obtain error result information, wherein the core operation of the neural network decoder is the multiply–accumulate operation of unsigned fixed-point numbers obtained by means of numerical value quantization processing (132). According to the quantum error correction decoding system using the neural network decoder, the core operation of the neural network decoder is the multiply–accumulate operation of the unsigned fixed-point numbers obtained by means of numerical value quantization processing, thereby minimizing the data volume and the computation amount required by the neural network decoder to better meet the requirement of real-time error correction.
