NVIDIA Ising Decoding Cuts Color Code Logical Error Rates by Over 300x | NVIDIA Technical Blog

What this post added

Introduced the NVIDIA Ising Decoder ColorCode 1 Fast, an AI-based pre-decoder utilizing 3D CNNs, which achieves over 347.7x better logical error rate (LER) and 7.3x faster runtime compared to the state-of-the-art Chromobius decoder for specific parameters. This contribution enables real-time decoding for color codes by accelerating and improving decoder accuracy, and provides open-source resources including model weights, training recipes, and data generation tools using cuQuantum and cuStabilizer.
