However, environmental noise arising from system-environment interactions severely limits the performance of such resources through decoherence. While significant progress has been made in mitigating Markovian noise, the extent to which non-Markovian noise can be mitigated remains poorly understood. We demonstrate that Heisenberg Scaling, the ultimate quantum limit on measurement precision, can be recovered in quantum metrology under non-Markovian noise by leveragi","authors_text":"Bakmou Lahcen, Ke Zeng, Kok Chuan Tan, Yu Jiang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"quant-ph","submitted_at":"2025-01-03T17:37:15Z","title":"Restoring Heisenberg-Limited Precision in Non-Markovian Open Quantum Systems via Dynamical Decoupling"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2501.01917","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":"sha256:21d57046b9c3fb3dfddd162908b99531f562d49f721fb605fa9b90d270030fb9","target":"record","created_at":"2026-07-05T09:56:43Z","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":"ce3fa99ee2485308e2d0c98201b4ae372232a79025776ffbb7d1b3187181dccc","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"quant-ph","submitted_at":"2025-01-03T17:37:15Z","title_canon_sha256":"072257b12a95b0210576f9fb2e04dc5c8abff645aa69f6efda367df0724cba61"},"schema_version":"1.0","source":{"id":"2501.01917","kind":"arxiv","version":1}},"canonical_sha256":"1cedd5bfcafa61dfd80a10e4aa5d1999389e9de4506cafc08a9a4a86a0f3a20d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1cedd5bfcafa61dfd80a10e4aa5d1999389e9de4506cafc08a9a4a86a0f3a20d","first_computed_at":"2026-07-05T09:56:43.391942Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:56:43.391942Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"R+OzOf/vCBOSFsQ90D+zrn4jSc1W9FGOucfpbD0lDmHOTS1zLGDZB3mKmDCiesiV+pYk5V2iXwUvSeZL+28FCw==","signature_status":"signed_v1","signed_at":"2026-07-05T09:56:43.392523Z","signed_message":"canonical_sha256_bytes"},"source_id":"2501.01917","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:21d57046b9c3fb3dfddd162908b99531f562d49f721fb605fa9b90d270030fb9","sha256:e37b964656dcf0526ce7f9bfb839a17090e0b13768e9bfacf4e3fdc5bfb03dcc"],"state_sha256":"96d0ef2dccb199c92598887b9ff50b46dcdac35119648ba27103746510793b11"}
