Low-Latency Belief-Propagation Decoding of Quantum LDPC Codes with Reinforcement-Learned Scheduling
Mohsen Moradi, Ghilas Aissou, Taejoon Kim +2
Belief propagation (BP) is attractive for quantum low-density parity-check (QLDPC) decoding because of its low complexity and low latency, but short cycles and degeneracy can limit…
Learned Parallel Bit-Flipping Sequential Belief Propagation Decoding of Quantum LDPC Codes
Mohsen Moradi, Taejoon Kim, Remi A. Chou
Quantum low-density parity-check (QLDPC) codes are promising candidates for low-overhead fault-tolerant quantum computation, but their practical use requires fast, low-complexity,…
Conflict-Free Color-Clustered Sequential Belief-Propagation Decoding of Quantum LDPC Codes via Reinforcement Learning
Mohsen Moradi, Taejoon Kim, Remi A. Chou
Belief-propagation (BP) decoding for quantum low-density parity-check (QLDPC) codes is attractive due to its low complexity and low latency, but it is often limited by short cycles…
Lifted-Product QLDPC Codes in the Polynomial Domain
