We demonstrate a mechanism that is able to transfer non-classical features imprinted on the state of a matter-wave system to an optomechanical device, transducing them into distinctive interference fringes. This provides a reliable tool for the inference of quantum coherence in the particle beam. Moreover, we discuss how our system allows for intriguing perspectives, paving the way to the construction of a device for the encoding of quant","authors_text":"Andr\\'e Xuereb, Hendrik Ulbricht, Mauro Paternostro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-08-16T08:19:10Z","title":"Optomechanical interface for probing matter-wave coherence"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1308.3576","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:b61d3028acf1a4b4c5818c358db95ef24a94028dfb3ed94768e0cf6392af14a2","target":"record","created_at":"2026-05-18T03:05:08Z","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":"afcd39348d556b2bb861445ee881962d20e243aa95af0790440ac3812be30e8b","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-08-16T08:19:10Z","title_canon_sha256":"da2fea9402dd46e179745fb2e6db720ccd15815da9a2acd672a0b1d69fb32c9e"},"schema_version":"1.0","source":{"id":"1308.3576","kind":"arxiv","version":2}},"canonical_sha256":"7d6f8b2fe9622a5e091e56f243bb411d58c6c424589b28661843446163d9b59e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7d6f8b2fe9622a5e091e56f243bb411d58c6c424589b28661843446163d9b59e","first_computed_at":"2026-05-18T03:05:08.474907Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:05:08.474907Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Bh060BQHBj3hbql/VtSE51vj3Ye6cp+VyJGrpsnzqAZfm2QUwqmJ/XCbX27QgiinyuFUOXq2SHPvsNUnsWcUDA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:05:08.475561Z","signed_message":"canonical_sha256_bytes"},"source_id":"1308.3576","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b61d3028acf1a4b4c5818c358db95ef24a94028dfb3ed94768e0cf6392af14a2","sha256:c501d87dfcf291b9ff756424218354db8bfa265715149ef90bdca442308c1164"],"state_sha256":"a55c0cb3acb3a6d7d6d369ba9e8c1419f043bc5a943c38acdb7303b76adb2816"}
