The explicit use of the continuous-variable formalism facilitates significantly the analysis of entanglement between different modes, reducing it to the study of the properties of a final covariance matrix which can be found analytically. Furthermore, it allows to study matter-light interfaces for mixed states, adapting the formalism to the experimental situations in which the initi","authors_text":"Anna Sanpera, Carles Rod\\'o, Julia Stasi\\'nska, Simone Paganelli","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-02T17:12:02Z","title":"A continuous-variable formalism for the Faraday atom-light interface"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1007.0403","kind":"arxiv","version":3},"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:eb15900330bf17b29f4e459b629283d8c35b5465c50cff32a3024112773e0f42","target":"record","created_at":"2026-05-18T04:19:22Z","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":"3e5b721553ea4dd54530dbaae726d779ee0e838c4f7b6334a0e101679273561f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2010-07-02T17:12:02Z","title_canon_sha256":"659be7a03f2616b04748f0930c7c58558419f7c09f51d068ec53c16d9d03800a"},"schema_version":"1.0","source":{"id":"1007.0403","kind":"arxiv","version":3}},"canonical_sha256":"0388e88393615e04511e8a4caf01c97fdc8bb514b655d41093b7de4d384e407c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0388e88393615e04511e8a4caf01c97fdc8bb514b655d41093b7de4d384e407c","first_computed_at":"2026-05-18T04:19:22.223012Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:19:22.223012Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qR7sW69DnH94lVMzQ/bZWwTZEj5H/K5II0QoawvwTQCmnc3Mn903m3Mwg0KZnu8ZaO1m8tkg6m0A2t6xSIHuDA==","signature_status":"signed_v1","signed_at":"2026-05-18T04:19:22.223634Z","signed_message":"canonical_sha256_bytes"},"source_id":"1007.0403","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:eb15900330bf17b29f4e459b629283d8c35b5465c50cff32a3024112773e0f42","sha256:b2ebde5375f7ed66afa14a63867f9d4bb41ff4dd1de6e7c5896d7a022458df87"],"state_sha256":"c023b87db66ccea39c5b368f2850f920f638191c3cbcf8c6487094a8a039caf0"}
