The scheme utilises cavity QED effects to selectively enhance a Frank-Condon transition, deterministically preparing a single Fock state of a polar phonon mode. By coupling the phonon mode to an antenna, the resulting excitation is then radiated to the far field as a single photon with a frequency matching the phonon mode. By combining macroscopic QED calculations with methods from open quantum system theory, we show that optimal parameters to generate these MI","authors_text":"Angel Rubio, Jake Iles-Smith, Mark Kamper Svendsen, Martijn Wubs, Nicolas Stenger","cross_cats":["cond-mat.mes-hall"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2024-05-21T13:25:35Z","title":"On-demand heralded MIR single-photon source using a cascaded quantum system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.12777","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:cc9c275e1219858be6bbc08160f16201062f557ab45f7c34552c50f044e9726e","target":"record","created_at":"2026-07-05T08:21:25Z","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":"4a891d719124c53e163d828cd267a4efa7f722e25fb5e8e12cc8b0521a306598","cross_cats_sorted":["cond-mat.mes-hall"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"physics.optics","submitted_at":"2024-05-21T13:25:35Z","title_canon_sha256":"67454232ec35e88db80f25eeca0215ca5718ab5ab55ab56f4bd46a9ec4e43496"},"schema_version":"1.0","source":{"id":"2405.12777","kind":"arxiv","version":1}},"canonical_sha256":"92e1f0bb2ce56f7e8a5b49071f0890a0cd7a3a3e688e667c736d02fad6d682e2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"92e1f0bb2ce56f7e8a5b49071f0890a0cd7a3a3e688e667c736d02fad6d682e2","first_computed_at":"2026-07-05T08:21:25.743829Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:21:25.743829Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"u8bo+HGNdE7YJZYtDYPOHHOavlyUibBqS+vqCxjekWU20z0asXDSTj08JxkxDbzf2LL2ztPkFLTmbD39+7AxAw==","signature_status":"signed_v1","signed_at":"2026-07-05T08:21:25.744331Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.12777","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:cc9c275e1219858be6bbc08160f16201062f557ab45f7c34552c50f044e9726e","sha256:74bddfa648d797d076465b0b59c027c2577017b70682a714cc365df4e1528c94"],"state_sha256":"532b1be7e348d74869be41f18d0420ce97a703decbe46fbbec0c27e3939c79dd"}
