The quantum states are discriminated by their different cavity transmission levels. A Bayesian update formalism is used to estimate state occupation probabilities as well as transition rates. We stabilize the balanced two-atom mixed state, which is deterministically inaccessible, via feedback control and find very good agreement with Monte-Carlo simulations. On average, the feedback loops achieves near optimal conditions by steering the system to t","authors_text":"Artur Widera, Dieter Meschede, Miguel Martinez-Dorantes, Ren\\'e Reimann, Seokchan Yoon, Stefan Brakhane, Tobias Kampschulte, Wolfgang Alt","cross_cats":["physics.atom-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-06-14T17:12:18Z","title":"Bayesian feedback control of a two-atom spin-state in an atom-cavity system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1206.3184","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:e29d7a18b4ffab0a6b716e435e0cb9e6641c8db50d3f4dfa8ba49d75bca35d54","target":"record","created_at":"2026-05-18T03:38:23Z","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":"1f2c1a3eef827b6d7ccd17b4e1a5d0d5216256c7783a73a73b794a868a1419ce","cross_cats_sorted":["physics.atom-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2012-06-14T17:12:18Z","title_canon_sha256":"fdfe0ba17c4024bee01c09d8283e6b22f21213b2b3a8c689da677db7b4e25073"},"schema_version":"1.0","source":{"id":"1206.3184","kind":"arxiv","version":1}},"canonical_sha256":"5c9960af3b97c64d6b636d01f9a0fb57ab7af592ae1f8d5c717610f7130b160c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5c9960af3b97c64d6b636d01f9a0fb57ab7af592ae1f8d5c717610f7130b160c","first_computed_at":"2026-05-18T03:38:23.430150Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:38:23.430150Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"bFt/+9DNMhvp4pIyyLHZb3ovQ1j/usAVkDJ0+n7W/GF9VQZ34e1L5dEg6x9XysCHFE2Tw7ody/PxhAHf6t17BQ==","signature_status":"signed_v1","signed_at":"2026-05-18T03:38:23.430615Z","signed_message":"canonical_sha256_bytes"},"source_id":"1206.3184","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:e29d7a18b4ffab0a6b716e435e0cb9e6641c8db50d3f4dfa8ba49d75bca35d54","sha256:42bb1ab3669ec0146d66e0a912e122c43828f2edb4ed858d134f62c602e5e69e"],"state_sha256":"d10652164589ac447cd8b08ffeaec849f5e3912206da77960fc2717e0c906dc5"}
