However, previous methods usually have a common assumption that detection noise levels should be below the intrinsic sensitivity provided by quantum resources. Here we report the first demonstration of Fano resonance between coupled alkali-metal and noble gases through rapid spin-exchange collisions. The Fano resonance gives rise to two intriguing phenomena: spin amplification and deamplification, which serve as crucial resources for enha","authors_text":"Dmitry Budker, Min Jiang, Xinhua Peng, Ying Huang, Yuanhong Wang, Yushu Qin","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-09-01T00:09:08Z","title":"Enhanced quantum sensing with amplification and deamplification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2309.00177","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":"sha256:122ed25f84bd6ff04c10b548ed1befe23cb912fa9a226e434d88ee1cd1789ff5","target":"record","created_at":"2026-07-05T06:46:53Z","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":"41375ecfccaeeb0c431aed469bbfb1e5dee7ebe3e2b0e9b847df220955acc8e6","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-09-01T00:09:08Z","title_canon_sha256":"744cecfa2bda85c2568ba981260e63a605f47a1c587764786e99703746d7cf66"},"schema_version":"1.0","source":{"id":"2309.00177","kind":"arxiv","version":1}},"canonical_sha256":"9fb301cd440902fdb12549b03ec2988b9ad95cf510247292f19a281522c85a3a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9fb301cd440902fdb12549b03ec2988b9ad95cf510247292f19a281522c85a3a","first_computed_at":"2026-07-05T06:46:53.383202Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T06:46:53.383202Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"PAwhx0MTz+T1VtxPbBdxrt2JAlF6ydmbGqQ3CsNGAGx046drhftrQQQUqjrVm+idap4UM0S2xq2Em3pwUpPUDA==","signature_status":"signed_v1","signed_at":"2026-07-05T06:46:53.383651Z","signed_message":"canonical_sha256_bytes"},"source_id":"2309.00177","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:122ed25f84bd6ff04c10b548ed1befe23cb912fa9a226e434d88ee1cd1789ff5","sha256:52fad047851346de0e7e8c42c75f819cfba91bca797045d78f012e0d3ec92d94"],"state_sha256":"ab8c2a207f3ac08d4c42b38886a8e3420c07c5b947760600a3083dc07f8c0720"}
