This stems from the fact that any measuring apparatus that is supposed to measure a physical observable will always yield a real number. However, reality of eigenvalue of some operator does not mean that it is necessarily Hermitian. There are examples of non-Hermitian operators which may admit real eigenvalues under some symmetry conditions. However, in general, given a non-Hermitian operator, its average value in a quantum state is a complex number and there are only very limited met","authors_text":"Arun Kumar Pati, Urbasi Sinha, Uttam Singh","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-06-11T19:35:52Z","title":"Measuring Non-Hermitian Operators via Weak Values"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.3007","kind":"arxiv","version":2},"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":"sha256:5488d1c07e086e9ccd92c0a7bdbd181f397fa2ad8d94d02050789d040908140b","target":"record","created_at":"2026-05-18T01:25:03Z","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":"7257051ac3b53a5c217d24d5cf740bbe53e47eb5745043d9751a0dde44972e52","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-06-11T19:35:52Z","title_canon_sha256":"65047efb66760df661eca0650bb4ed27ac0c623c00c11e8098a58c8ae8450df4"},"schema_version":"1.0","source":{"id":"1406.3007","kind":"arxiv","version":2}},"canonical_sha256":"748d2d253dc14abba713d58b786ace3594b32982f8d70e9df29b9e4e51fd4b8c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"748d2d253dc14abba713d58b786ace3594b32982f8d70e9df29b9e4e51fd4b8c","first_computed_at":"2026-05-18T01:25:03.514124Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:25:03.514124Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"pVN/J5SXwP6QZck3GuMYRP1pKHRaxmDNDRwFvoV//02Czaq/+8p2Or1YSBIEnpNSWLSobIqhczOdeZynx7rrAQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:25:03.514821Z","signed_message":"canonical_sha256_bytes"},"source_id":"1406.3007","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5488d1c07e086e9ccd92c0a7bdbd181f397fa2ad8d94d02050789d040908140b","sha256:29f599b13f6f725eeb8500660563dcdffd208eab08c7035f9c6e96cce238b15f"],"state_sha256":"5febe1ddb75a6045333d1f9ddf5d325c3e349f031f2160b906427742f59d8fee"}
