The qudits are encoded and manipulated in the frequency spectrum of broadband energy-time entangled photons by taking into account a spatial light modulator. The latter allows to discretize the spectrum into bins. By controlling each frequency bin individually, the generation of maximally and non-maximally entangled qutrits is verified through quantum state tomography.","authors_text":"Andr\\'e Stefanov, B\\\"anz Bessire, Sacha Schwarz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-09-17T15:58:55Z","title":"Experimental violation of a d-dimensional Bell inequality using energy-time entangled photons"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1409.5039","kind":"arxiv","version":2},"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":"sha256:01292f74f066057ac7f059807a2b283a6d05e5625f3a9b9f9ac662ea75eb7830","target":"record","created_at":"2026-05-18T01:35:35Z","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":"fb19961186655547bb95555d3e277d2a221aaf7d3bfb569d0f55cf6ca9ef422d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-09-17T15:58:55Z","title_canon_sha256":"09087a4e86003868359f14bde73ac3e5ff3a71bdf8f9b0a01c1389503975231d"},"schema_version":"1.0","source":{"id":"1409.5039","kind":"arxiv","version":2}},"canonical_sha256":"8b15cfe54e68f3af98a4983c033061abff093cb9f88c25cd366e9d571a84133d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"8b15cfe54e68f3af98a4983c033061abff093cb9f88c25cd366e9d571a84133d","first_computed_at":"2026-05-18T01:35:35.294095Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:35:35.294095Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"CPnrS3yPkg6K33Lxhx52JizBD5W9itVhn4OgTRbPoS1zubNY1trxDVS1Cid3sjtx9+GHb5OpU1/c23hQ3h2SBw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:35:35.294685Z","signed_message":"canonical_sha256_bytes"},"source_id":"1409.5039","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:01292f74f066057ac7f059807a2b283a6d05e5625f3a9b9f9ac662ea75eb7830","sha256:21471a64d2d0b5bf9ee81f5d6e085fadf68c70421e059228b9cb6e642f86a28e"],"state_sha256":"9e62832576bf4715fc16dd5552c01f88113d3dae512567c52328ad2e29ec2422"}
