Using a high quality guided-wave heralded single- photon source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 $\\pm$ 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optics gyroscope is discussed.","authors_text":"Daniel Barry Ostrowsky (LPMC), Guillaume Bertocchi (LPMC), Olivier Alibart (LPMC), Pascal Baldi (LPMC), S\\'ebastien Tanzilli (LPMC)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-12-30T16:02:18Z","title":"Single-photon Sagnac interferometer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1312.7754","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":"sha256:5ebc8f6118bf5c109160a5b1abdea05ffda41ae288da250a55cb40412ba2a673","target":"record","created_at":"2026-05-18T03:03:33Z","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":"07acf0b82fd2bd1578f827d534e7cc550a32c206fcec7226ee3b7a62c686e9c1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-12-30T16:02:18Z","title_canon_sha256":"8aa89a062d423394c8d87ef0f76738ad7670d6a1da5ffab41ce5bcae94ce4aaa"},"schema_version":"1.0","source":{"id":"1312.7754","kind":"arxiv","version":1}},"canonical_sha256":"36f9ef63dec8f6800cc5422659582290a0d237c2c32fc4a1aba658470abfca5c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"36f9ef63dec8f6800cc5422659582290a0d237c2c32fc4a1aba658470abfca5c","first_computed_at":"2026-05-18T03:03:33.813814Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:03:33.813814Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rx2pvq9u7iAE/iNd+1tKvrC1CgniuhLvSPXCy2AiAe5Rnw0GMA/Uw+6SAEeiZeW5AhdL5ZN3Qjvd357Y4xUeBg==","signature_status":"signed_v1","signed_at":"2026-05-18T03:03:33.814558Z","signed_message":"canonical_sha256_bytes"},"source_id":"1312.7754","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5ebc8f6118bf5c109160a5b1abdea05ffda41ae288da250a55cb40412ba2a673","sha256:3822bd7a1ee2938b6a2b9a702d9bac0a50935b6c6928247b1bdaf6934eb4eb2e"],"state_sha256":"ac8a6da4e8a52c17b88ae715a8b2fae5ad674db26ee1d5f07d78428360d8665d"}
