This research presents a lightweight CNN pre-decoder that significantly reduces the computational load for real-time quantum error correction in surface codes. By separating spatial and temporal error patterns into parallel processing branches, QuantiSpect achieves sub-microsecond decoding speeds while using fewer parameters than existing models on standard GPU hardware. The work represents a practical optimization of established pipelines rather than a fundamental theoretical shift, offering immediate benefits for scaling fault-tolerant quantum systems.

QuantiSpect cuts 3D convolution load with a lightweight CNN pre-decoder, accelerating quantum error correction for scalable surface codes.

Researchers at Beijing Academy of Quantum Information Sciences and QuSpect Technology Co., Ltd. have developed QuantiSpect, a new pre-decoder designed to address a critical bottleneck hindering large-scale quantum computing: real-time decoding. The work introduces a “lightweight 3D convolutional neural network (CNN)” that locally corrects errors before they reach a global decoder, potentially achieving decoding speeds under one microsecond. This pre-decoder builds upon the decoding pipeline of Chamberland et al., optimizing an established approach rather than proposing a completely novel method. On a benchmark using a unified A100 GPU, QuantiSpect matched the performance of a baseline model while using approximately 2.71 times fewer parameters (3 million vs. 8.4 million) and 2.84 times fewer per-voxel convolutional operations (16 million vs. 47 million). Achieving sub-microsecond decoding latencies is now within reach thanks to the…
