The conventional detection schemes require repeated measurement on a large number of identically prepared systems. This is hard to achieve in practice when dealing with large-scale entangled quantum systems. In this letter we develop a novel method by formulating verification as a decision procedure, i.e. entanglement is seen as the ability of quantum system to answer certain \"yes-no questions\". We show that for a variety of large quantum states even a single copy suffices to detect entangle","authors_text":"Aleksandra Dimi\\'c, Borivoje Daki\\'c","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-05-18T17:49:07Z","title":"Single-copy entanglement detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.06719","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":"sha256:8a93729de529eff235d6de1f71f4ee197cc96171a405045f845caf11c4621a51","target":"record","created_at":"2026-05-18T00:21:55Z","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":"3bb1fc7de892f8f818f9f4bde0c5891a42b1fa8a861f0f1549e83357c82d5c30","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2017-05-18T17:49:07Z","title_canon_sha256":"8d16ee2cecace390170bec1e841a4af26533d562efc27b17f338b3cad24e3536"},"schema_version":"1.0","source":{"id":"1705.06719","kind":"arxiv","version":2}},"canonical_sha256":"adedb635cbab702ced84dcfa0226dafd73177f12628b878e9111730ce7b4b7db","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"adedb635cbab702ced84dcfa0226dafd73177f12628b878e9111730ce7b4b7db","first_computed_at":"2026-05-18T00:21:55.003997Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:21:55.003997Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BLT7EJyua+XCrFhceA38wayn7yQY6g1sFQUMpc9XEiAmyI3zQckzJUowUKx1l63ChRNzJLn2mBSnrYPnJJXLAw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:21:55.004542Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.06719","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8a93729de529eff235d6de1f71f4ee197cc96171a405045f845caf11c4621a51","sha256:59ba5016b60fe982841c05143a6104cb26852ed134d09a95d87e7708f7860fb0"],"state_sha256":"8c0a18e87b9fec60bb8094e1b5861c49538e9c6ff837321c7118c6224245dade"}
