In this paper we deepen our understanding of this nexus through high-level analysis of a class of quantum memory models that we have previously proposed, which implement continuous-time versions of well-known stabilizer codes in autonomous nanophotonic circuits that require no external clocking or control. We show that the presence of the gauge subsystem in the nine-qubit Bacon-Shor code allows for an optimized layout of the corresponding nano","authors_text":"Gopal Sarma, Hideo Mabuchi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-12-14T18:53:43Z","title":"Gauge subsystems, separability, and robustness in autonomous quantum memories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1212.3564","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":"sha256:886272c71085aaaa194e64d33fc5fd36cd6d7140e7a442d0094259b6c974f6a2","target":"record","created_at":"2026-05-18T01:52:38Z","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":"4c81d6e889b399ec049a2611a4ffdd7824fda816bbf94ee7ec91476847fe7273","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-12-14T18:53:43Z","title_canon_sha256":"6b7070d92098630fe6ee56385d4655e6f0f7807911b126b445301645368db735"},"schema_version":"1.0","source":{"id":"1212.3564","kind":"arxiv","version":1}},"canonical_sha256":"925d5eb3b6d888f9146904bcc5cedd941ef596b2585bfe8576f811b337d36411","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"925d5eb3b6d888f9146904bcc5cedd941ef596b2585bfe8576f811b337d36411","first_computed_at":"2026-05-18T01:52:38.094073Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:38.094073Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BzxzIwP8psTTd9PbjxPx6JfLAQWTm0maluG4bZX3w8oUOZvFtAV4u1k26MJwlg+XAGeSJkOhMdNUjPqYKEy3Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:38.094746Z","signed_message":"canonical_sha256_bytes"},"source_id":"1212.3564","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:886272c71085aaaa194e64d33fc5fd36cd6d7140e7a442d0094259b6c974f6a2","sha256:10d7c1edccf07c410687f10d9589591aa378135fc08b60eb23fd9587d7083e10"],"state_sha256":"9646db35410c1e170518018c58f614ba1d791034542b7a4bab0dd54509264007"}
