The setup is simple, of low cost, exhibits inherently high directional light emission and allows for a flexible arrangement. By measuring the photon statistics and spatial two point intensity correlations in the far field we show that the setup exhibits all characteristics of a gaussian random source.","authors_text":"Joachim von Zanthier, Steffen Oppel, Thomas Mehringer","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-11-28T15:09:23Z","title":"An optical multimode fiber as pseudothermal light source"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.09161","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":"sha256:938691b227927099edfa30b0d4d55e1b3d9407a8f1a24be66c542e3c0a52f412","target":"record","created_at":"2026-05-18T00:39:01Z","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":"322deb68361fd3ddea75bd03001de0556568e510d5bd111356e05c228870f3ea","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-11-28T15:09:23Z","title_canon_sha256":"288ffecb2c22a144faeb81f786ed25601adbd9d3202483585ea28fa1e5cc67c3"},"schema_version":"1.0","source":{"id":"1611.09161","kind":"arxiv","version":1}},"canonical_sha256":"777f2e0806b34e4e48658e44a2e5dddaa18656ba2757d80afeec22e29f6f779d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"777f2e0806b34e4e48658e44a2e5dddaa18656ba2757d80afeec22e29f6f779d","first_computed_at":"2026-05-18T00:39:01.031477Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:39:01.031477Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yDoZnX0C8I2YlPjycsTHLsaoIM4M18kmuHb/gnEN5wUmk0zup6+vOtn4rP+FJ/YNcLiUHGzxlvtiW6SGhAaUAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:39:01.031975Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.09161","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:938691b227927099edfa30b0d4d55e1b3d9407a8f1a24be66c542e3c0a52f412","sha256:0a7d4f9166ca4e31ef01a8b685941c34f99eb7acfe12c4e420289bc0af12d758"],"state_sha256":"0a16424bbc9346b0a9873e3ff0333a6439e5f54779ed94f4cac640fffeac65b3"}
