Zero-G: A Pre-Decoder-Aware Decoder for Quantum Error Correction
Zero-G is presented, a strong decoder designed for use alongside pre-decoders that achieves a $10\times$ latency improvement over existing strong decoders at matching accuracy, with worst-case sub-350ns decoding at code distances up to d=15, while scaling to 640 logical qubits on a single 128-core CPU and 32 logical qu...
