Our research demonstrates that non-Gaussian states, particularly the photonsubtraction-then-addition (PSA) state, exhibit the best sensitivity in the presence of symmetric noise. Additionally, higher-order of Bose operator of non-Gaussian states provide better sensitivity for symmetric noise. OAM can mitigate the deterioration of noise, making it possible to estimate small phase shifts ","authors_text":"Jie Song, Jin-Wei Gao, Jin-Xuan Han, Ruo-Qi Li, Yong-Jian Chen, Yong-Yuan Jiang, Zhong-Hui Yuan","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-12-04T07:19:59Z","title":"Orbital angular momentum-enhanced phase estimation using non-Gaussian state with photon loss"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2312.01684","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":"sha256:72be56c0c8044c20dd37caf865ae0bb998c5d2c250152c2204e18bf862001685","target":"record","created_at":"2026-07-05T07:19:58Z","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":"268ae74d68eb7c1c9779b2554f25a5d4bbe119b325598b9898e1c3f36f9d41fb","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2023-12-04T07:19:59Z","title_canon_sha256":"1e4fabfef0450cb4b7ee10ea3f562838cd5c91488732abf78d28a30c8b4f9ac6"},"schema_version":"1.0","source":{"id":"2312.01684","kind":"arxiv","version":1}},"canonical_sha256":"db044f2728e9ebbb0e92795d5bb0645ad5466b262d110abbc78d266fb281b816","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"db044f2728e9ebbb0e92795d5bb0645ad5466b262d110abbc78d266fb281b816","first_computed_at":"2026-07-05T07:19:58.113747Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:19:58.113747Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xh2ktaMxSyTawPGwfe4Ivije5uCHvd7A6IMojrdeM+7cad6avgBERA7OHV5N9fFFuZ15la7UOXg520tYpSJ5Aw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:19:58.114460Z","signed_message":"canonical_sha256_bytes"},"source_id":"2312.01684","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:72be56c0c8044c20dd37caf865ae0bb998c5d2c250152c2204e18bf862001685","sha256:7b07d003f70d87b52e6c4671a53f539bbc5891990988e998b911c3c9f8684664"],"state_sha256":"8b2ff1bc8b34c0809a44d779fe769528ceeca239c8284b833949cfe213037c61"}
