Our decoder employs a set of automorphisms of the quantum code and an ensemble of belief propagation (BP) decoders. Each BP decoder is given a syndrome which is transformed by one of the automorphisms, and is run in parallel. For quantum codes, the accuracy of BP decoders is limited because short cycles occur in the Tanner graph and our approach mitigates this effect. We demonstrate decoding accuracy comparable to BP-OSD-0 with a lower time overhead for Quantum Reed-Muller (QRM) ","authors_text":"Dan E Browne, Hasan Sayginel, Mark Webster, Stergios Koutsioumpas","cross_cats":["cs.IT","math.IT"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-03-03T16:58:24Z","title":"Automorphism Ensemble Decoding of Quantum LDPC Codes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.01738","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:858964c234e04246cb482ec78c45fcf1a26a2890542377efe67e10fb970c17be","target":"record","created_at":"2026-07-05T10:23:13Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3f9b8086ef6981e2a94ef654b91a02859f86e28ee48e09265bbbf383082202d9","cross_cats_sorted":["cs.IT","math.IT"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-03-03T16:58:24Z","title_canon_sha256":"6e34d13717621013467cfb80a6a1e12571047facff7e8b0e62048cbbf521538b"},"schema_version":"1.0","source":{"id":"2503.01738","kind":"arxiv","version":1}},"canonical_sha256":"6d03a01a68f15a6bb9eca39be3d41ba813506fbd75938efadf239fe1704288ca","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6d03a01a68f15a6bb9eca39be3d41ba813506fbd75938efadf239fe1704288ca","first_computed_at":"2026-07-05T10:23:13.722173Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:23:13.722173Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Jc4BlzPEZqAPU512xCTLFPLTUGSAB75aIfXXfl05xyTN47AoykK5omEHgHp3yQc1gaahl6TRBLEy6Pg7Jb95Dg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:23:13.722853Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.01738","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:858964c234e04246cb482ec78c45fcf1a26a2890542377efe67e10fb970c17be","sha256:ecbffd1b66ac19290f0d822963f1d831747190f5224a02536392f0f7e6ec0417"],"state_sha256":"a7da64d7c953c93d6a323898875b07d40772e726f6ef7a7399fb3e43bfe44fd5"}
