A spin superposition state will acquire a phase induced by the target field, and we can estimate the field strength from this phase. Recent studies have aimed at improving sensitivity through the use of quantum error correction (QEC) to detect and correct any bit-flip errors that may occur during the sensing period. Here, we investigate the performance of a two-qubit sensor employing QEC and under the effect of energy relaxation. Surprisingly, we find that the standard QEC technique to de","authors_text":"Simon Benjamin, Yuichiro Matsuzaki","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-11-30T17:01:50Z","title":"Magnetic field sensing with quantum error detection under the effect of energy relaxation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1611.10264","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:b9f2c1f06d912e1315a29e5b62e559614a2a7d5665a4b1f391bf4246236c1380","target":"record","created_at":"2026-05-18T00:47:07Z","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":"c319df3329a0c52308ff8ac3100edf54f43a1ae81936ca87890d2e2235bd1854","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-11-30T17:01:50Z","title_canon_sha256":"7aef0d1be2c1404f057854239919e4e3c8350e0e5e171495e5a063a83e1aad67"},"schema_version":"1.0","source":{"id":"1611.10264","kind":"arxiv","version":1}},"canonical_sha256":"9557d9f6b73d8c56f894694a04b6ec96b75996e93f474c856a48c7054b208b1f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9557d9f6b73d8c56f894694a04b6ec96b75996e93f474c856a48c7054b208b1f","first_computed_at":"2026-05-18T00:47:07.723989Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:47:07.723989Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lAr38lwOh4vRginTUO90w5ry4DCQP9ZYJy2gSlI+r4JVL+4aEvvKSyiaPl+/sxFlEJ7ilyaGFqiNONOeLkOhCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:47:07.724577Z","signed_message":"canonical_sha256_bytes"},"source_id":"1611.10264","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b9f2c1f06d912e1315a29e5b62e559614a2a7d5665a4b1f391bf4246236c1380","sha256:c9957497013ad4e077a28688599393bc26a1517bacda1ccd137a63a9b263123f"],"state_sha256":"3de4100ed16b01d4c912497fd7a8cb3c1fc3dd9ce4b5ed5dc77d916b96742a90"}
