The entanglement timescale is inversely proportional to the \"correlated uncertainty\" between the two subsystems, a quantity which we will define and analyze in this paper. Our result is still applicable when one of the subsystems started in an arbitrarily mixed state, thus it generalizes the well-known \"decoherence timescale\" while coupled to a thermal state.","authors_text":"I-Sheng Yang","cross_cats":["quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-07-18T18:00:08Z","title":"The Entanglement Timescale"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1707.05792","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":"sha256:5cc0d9ef4edb156075cebdcccfb0dd263534daed227708556ff70dc62f198c06","target":"record","created_at":"2026-05-18T00:20:39Z","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":"f8654fff9aa57d046daea3abb270897b24ce0557ad74c6f2e72448856e9eacb1","cross_cats_sorted":["quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-th","submitted_at":"2017-07-18T18:00:08Z","title_canon_sha256":"5d7cafc447d808145b3f964e661b6fbe65331552264b47ffbc0cc16910ac7cc9"},"schema_version":"1.0","source":{"id":"1707.05792","kind":"arxiv","version":2}},"canonical_sha256":"62169448c227cd795659e3b2bb167fce74db1b90d76605a30ee782af79574f9c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"62169448c227cd795659e3b2bb167fce74db1b90d76605a30ee782af79574f9c","first_computed_at":"2026-05-18T00:20:39.397671Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:20:39.397671Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"92Mdq0uQDVhsXYHAj/jsfs2x6al3dEh7bdJOjn+0eQP+oq72aRQKYFhDyiMxjwUiTlsZvOTzT2h+XwZ1Y2t9Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:20:39.398382Z","signed_message":"canonical_sha256_bytes"},"source_id":"1707.05792","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5cc0d9ef4edb156075cebdcccfb0dd263534daed227708556ff70dc62f198c06","sha256:a1d7dbf16ef2982e9c76c1ef92e7695660a49d69a66868ad9094b1ce6a3a7058"],"state_sha256":"c227a49444ae436c638b97cd046e4d385c6f599b9de88f4f4ef0d0ad69bdcfda"}
