Promatch: Enabling Real-Time Decoding of Large Distance Surface Codes through Adaptive Predecoding

Promatch is an adaptive predecoder that enables real-time decoding of surface codes with distances up to 13, achieving the highest accuracy in the literature.

Efficient Syndrome Decoding for Heavy Hexagonal Quantum Error Correcting Codes using Machine Learning

This work proposes an efficient machine learning-based syndrome decoder for heavy hexagonal quantum error correcting codes, which achieves significantly higher threshold and pseudo-threshold values compared to the state-of-the-art minimum weight perfect matching decoder.

Efficient Iterative Decoding of Quantum Low-Density Parity-Check Codes Under Circuit-Level Noise

A sliding window decoder based on belief propagation with guided decimation is proposed to efficiently decode quantum low-density parity-check codes in the presence of circuit-level noise.
