Due to the continuous nature of the source, the choice of the duration of each measurement round effectively controls the average number of photon pairs participating in the Bell test. We observe a maximum violation of S= 2.01602(32) with average number of pairs per round of ~0.32, compatible with our system overall detection efficiencies. Systems that violate a Bell inequality are guaranteed to generate pr","authors_text":"Adriana Lita, Alessandro Cer\\`e, Antia Lamas-Linares, Christian Kurtsiefer, Jean-Daniel Bancal, Jianwei Lee, Le Phuc Thinh, Lijiong Shen, Sae Woo Nam, Thomas Gerrits, Valerio Scarani","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-05-08T04:21:38Z","title":"Randomness extraction from Bell violation with continuous parametric down conversion"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.02828","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":"sha256:9f5f80d7b376b4a10f8124783eb1f664ba069b284c76153705aa1acee0153089","target":"record","created_at":"2026-05-18T00:03:31Z","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":"80af69326f453b5b7a72a64aff5e764c9eb34ed5baa4b372c05b96fb5263bbca","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-05-08T04:21:38Z","title_canon_sha256":"41cb90bcf8122d32e653e1ecff85f4c1a279196e9b8d2f028b52dd6773fc51cb"},"schema_version":"1.0","source":{"id":"1805.02828","kind":"arxiv","version":1}},"canonical_sha256":"959a5b6ae7569f1f93338e68921504faf00d571359a6e64543eee2eac9671106","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"959a5b6ae7569f1f93338e68921504faf00d571359a6e64543eee2eac9671106","first_computed_at":"2026-05-18T00:03:31.978610Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:03:31.978610Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"V1IuJaTlo/XHtEzgAHPrh4du+6CaXM+luhvobGlHkt2S73PdmkLcarpkMugagVSRD+md2VhdnvjT4+3wNH8LCA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:03:31.979285Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.02828","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9f5f80d7b376b4a10f8124783eb1f664ba069b284c76153705aa1acee0153089","sha256:c9b48624d7a0cbd116b55040082f42ab90db0905aaec31f62618b35f6ee5579e"],"state_sha256":"85eea375ea30c2adf43e00de16376c7d6a75a4abc62011443079bd4d3af62bc4"}
