Classical LDPC design theory brought to quantum error correction

Caption

Selective orthogonality preserves classical LDPC design freedom. The resulting [[9216,4612,d]] code (d≤48) protects 4,612 logical qubits with 9,216 physical qubits, has girth 8, provides strong evidence of a minimum distance near 48, and shows a clear BP decoding waterfall close to the classical density-evolution benchmark
