Bias-Aware BP Decoding of Quantum Codes via Directional Degeneracy
Mohammad Rowshan
We study directionally informed belief propagation (BP) decoding for quantum CSS codes, where anisotropic Tanner-graph structure and biased noise concentrate degeneracy along prefe…

Single-Shot and Few-Shot Decoding via Stabilizer Redundancy in Bivariate Bicycle Codes
Mohammad Rowshan
Bivariate bicycle (BB) codes are a prominent class of quantum LDPC codes constructed from group algebras. While the logical dimension and quantum distance of \emph{coprime} BB code…
