Although these inequivalent maximal entangled states represent the same quantum correlation in the absence of noise, it is shown that the W state is more robust than the GHZ state through most noisy channels. Also, using measurement-induced disturbance measure, we obtain the analytical relations for the time evolution of quantum correlations in terms of the noisy parameter $\\kappa$ and remove its overestimating qua","authors_text":"Pakhshan Espoukeh, Pouria Pedram","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-09-23T16:29:58Z","title":"Quantum correlation evolution of GHZ and W states under noisy channels using ameliorated measurement-induced disturbance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1409.6658","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:f97b304414a17063f86de12156b1a3438a81364bc117889f73d895dee43488f6","target":"record","created_at":"2026-05-18T02:29:54Z","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":"c2f1f541147f2ab0ec8fb9bae0583fc8d1f978877789f9031dfcbd993e03e2fb","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2014-09-23T16:29:58Z","title_canon_sha256":"3a2cb55e9c0ce8165dc3daa0d0e85fc8ed54a0f15304f3f08b0b929225dc8ef0"},"schema_version":"1.0","source":{"id":"1409.6658","kind":"arxiv","version":1}},"canonical_sha256":"5abf534a2aed1e84d63793f8627312eba143b7de83176247329cabdd83049263","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5abf534a2aed1e84d63793f8627312eba143b7de83176247329cabdd83049263","first_computed_at":"2026-05-18T02:29:54.833835Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:29:54.833835Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5J0SufM6hK7eS5yIaMjl4wbq51pBMGpTz4ZYTuEevfUXXlBXk2ILju18UOcndfmEFEiMH5T5bmPRcdBmF/sfDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:29:54.834288Z","signed_message":"canonical_sha256_bytes"},"source_id":"1409.6658","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f97b304414a17063f86de12156b1a3438a81364bc117889f73d895dee43488f6","sha256:45d7a0500aff8075c55fbceb0cc8b74b5a68f97950ada73495cd17428117d540"],"state_sha256":"0a87ecc683a1c6416f1bc91f383ae12da6e4436cb37b6e37995028b8b90ead43"}
