Academic Achievements
- Developed explicit quantum LDPC codes from permutation matrices with strong error-correcting performance over depolarizing channels
- Designed codes avoiding short cycles in Tanner graphs to suppress error floors
- Achieved performance close to the hashing bound, reduced error floors in low-rate regimes, constructed large-girth codes, and discovered binary LDPC codes with sharp error-rate transitions
- Published results in npj Quantum Information (arXiv:2506.15636)
- Released open-source joint and degeneracy-aware BP decoder for non-binary LDPC quantum error correction on GitHub
- Made parity-check matrix data from the paper publicly available
