The necessary and sufficient conditions to classify the fully separable, biseparable, and genuine entangled states are explicitly given. The approach can be generalized to multipartite high-dimensional cases. For three-qubit mixed states, we propose two kinds of inequalities in terms of the expectation values of complementary observables. One inequality has advantages in entanglement detection of the quantum state with positive partial transpositions, and","authors_text":"Ming-Jing Zhao, Shao-Ming Fei, Ting-Gui Zhang, Xianqing Li-Jost","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-01-18T08:16:51Z","title":"Identification of three-qubit entanglement"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1301.4317","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":"sha256:4db0267c58463004ec53f9a4e3432a02b70dbf2a0729b5b51911bae9faf2f43c","target":"record","created_at":"2026-05-18T01:52:05Z","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":"66cfb3aa863ed2ef3e59acc2920c86a80b5f35c01c3bbb4468e8e406668cf890","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2013-01-18T08:16:51Z","title_canon_sha256":"575100f51a9360a4f04171f59e68313687cfcb2aed6a6098ef1a9f7a4d3f9f90"},"schema_version":"1.0","source":{"id":"1301.4317","kind":"arxiv","version":1}},"canonical_sha256":"ddb5e91343656a97affdd3b90de3eac68686e53291c36e571e5b3d8d935cee24","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ddb5e91343656a97affdd3b90de3eac68686e53291c36e571e5b3d8d935cee24","first_computed_at":"2026-05-18T01:52:05.937760Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:52:05.937760Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b4zIX+8rsRtuhYZG1Fb+LFaYkE/UzVZtyVoU2BT1AHspnHIs4LOLOrLe3DRIZnNGQZUww8wC+1GWqGC5+6NfCA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:52:05.938293Z","signed_message":"canonical_sha256_bytes"},"source_id":"1301.4317","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4db0267c58463004ec53f9a4e3432a02b70dbf2a0729b5b51911bae9faf2f43c","sha256:bf87a938f6e91f2c679225f0347eb467f7408e271edadda49424f4f23a3419de"],"state_sha256":"55d34e346c4bec99e6d7080aad1055495cbb7f48c95e1236dcf9d5c6a1ec3e1b"}
