We compute and compare three different criteria of quantumness, the $l_1$-norm of coherence, the Leggett- Garg inequality and a quantum witness based on the no-signaling in time condition. We show that all three quantum indicators decay exponentially in time as a result of the coupling to the thermal reservoir. We further demonstrate that the corresponding characteristic times are identical and given by the coherence half-life. These results quantify how violations of Leggett-Garg inequalities and nonze","authors_text":"Alexander Friedenberger, Eric Lutz","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-10-24T20:03:49Z","title":"Assessing the quantumness of a damped two-level system"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1610.07626","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":"sha256:83f507d88d87f1bdcf0333e942d9a87f611e64608cfd5159906331c117a2fbd5","target":"record","created_at":"2026-05-18T00:14:41Z","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":"98d46922ac4aa9be2489b0ce81bcc4cf2ed50cf8769ba21b9b4f2e9a4fa4f3f0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-10-24T20:03:49Z","title_canon_sha256":"7520159357969b98144eb5e9f3159598841d6265cc9c2aa1fd1d9536acca076c"},"schema_version":"1.0","source":{"id":"1610.07626","kind":"arxiv","version":1}},"canonical_sha256":"afcd7aeb1a0b94954ad3b1a47e2ee3f63d5cbe9aa5c61ac8abc6226e75357e65","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"afcd7aeb1a0b94954ad3b1a47e2ee3f63d5cbe9aa5c61ac8abc6226e75357e65","first_computed_at":"2026-05-18T00:14:41.402333Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:14:41.402333Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/r7FYEneZ89DmqlBAhugnH84XX2lLpSSfte4JSvogXmspOe3/TLlN4b/J0c1+XD/J042DnFYqUsyF73kOXU4AA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:14:41.402894Z","signed_message":"canonical_sha256_bytes"},"source_id":"1610.07626","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:83f507d88d87f1bdcf0333e942d9a87f611e64608cfd5159906331c117a2fbd5","sha256:9605cde1362dd10de68329b9bff34331465014649f4ebd91fef9b424330b84b4"],"state_sha256":"ada960d77ddd92d0802ecb3a6b0a44a12f2381b58d89e2d98cf04997d686bc8c"}
