As the indispensable resource, the method uses pairs of time-energy entangled photons. To accomplish the shaping, one photon of a pair undergoes temporal modulation according to the desired shape. Subsequent frequency-resolving detection of the photon heralds its entangled counterpart in a pure quantum state with a temporal shape non-locally affected by the modulation. We found conditions for the shape of the heralded photon to reproduce the modulation function","authors_text":"Denis Sych, Gerd Leuchs, Valentin Averchenko","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-10-12T17:20:02Z","title":"Heralded temporal shaping of single photons enabled by entanglement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.03794","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":"sha256:91adc60522fa646735548afb927335e50df13dc14e0d820dfccc6f2d0fbf7fa3","target":"record","created_at":"2026-05-18T00:32:44Z","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":"80d5df3c49a003c3861e1701f6d1e3857d1dcbade8074fc1d5710a4ffec6917f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-10-12T17:20:02Z","title_canon_sha256":"4a9928991343ddecdbca333ee881b1f59db36a4c1a24164858ef53f8e0561698"},"schema_version":"1.0","source":{"id":"1610.03794","kind":"arxiv","version":1}},"canonical_sha256":"961e1726fcaecf365b8a9650691b7a5417df9655f725b636c5fd89ded0422c70","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"961e1726fcaecf365b8a9650691b7a5417df9655f725b636c5fd89ded0422c70","first_computed_at":"2026-05-18T00:32:44.263103Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:32:44.263103Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ci3WSTlS82FJd7wF4/g/Aza4bWY6R+Kk9liRDIal0Aftq2UhwDJmf6Ilt5ZdXQTp5qzequYJR0sgaxkOrETfAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:32:44.263733Z","signed_message":"canonical_sha256_bytes"},"source_id":"1610.03794","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:91adc60522fa646735548afb927335e50df13dc14e0d820dfccc6f2d0fbf7fa3","sha256:9fa89bc31b3a7fcb32f2b169a1bd9f8d266869c7ec119e0f5d596614abee61a6"],"state_sha256":"07427d69a839df2bd30926ed3de1f0905fec4a6213d7666a8c4d61ce0c59b819"}
