To this end, a family of multipartite Bell inequalities is introduced basing on local projective measurements conducted by $N-k$ parties and applying a $k$-party Bell inequality on the remaining parties. Surprisingly, we find that most of the studied pure multipartite states involving e.g. cluster states, the Dicke states, and the Greenberger-Horne-Zeilinger states can violate our inequalities with only the use of t","authors_text":"Kamil Kostrzewa, Tamas Vertesi, Wieslaw Laskowski","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-05-14T11:00:50Z","title":"Closing the detection loophole in multipartite Bell experiments with a limited number of efficient detectors"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1805.05106","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":"sha256:1bfb65b01fe501f1ed681d362bb4f967576f5da3c503cf888ca0149057297478","target":"record","created_at":"2026-05-18T00:08:00Z","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":"03342e390d7d08c8ce760c00416df7f74c49fd8ef32d2ec26a4d17b8e98babfe","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-05-14T11:00:50Z","title_canon_sha256":"22f8e2e5512dbf8470471812b414be7a0253f577099296bfb0ae22fa47b16d26"},"schema_version":"1.0","source":{"id":"1805.05106","kind":"arxiv","version":2}},"canonical_sha256":"e3f9b77674c0c2d1f64d6a88d3eb4db5dfe9e5080fb9beda0a7934d37e472af9","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e3f9b77674c0c2d1f64d6a88d3eb4db5dfe9e5080fb9beda0a7934d37e472af9","first_computed_at":"2026-05-18T00:08:00.332513Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:08:00.332513Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xHW1Zampw8wSYwOF141ufVHHwXnY1Ks9e4xTjP/o8y2VjWyDWtaNTJCGoIrYTDAiKizaoVk2xCoeUur6VWUVDg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:08:00.333153Z","signed_message":"canonical_sha256_bytes"},"source_id":"1805.05106","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1bfb65b01fe501f1ed681d362bb4f967576f5da3c503cf888ca0149057297478","sha256:0e19f1f85e2d140d3a17b2b3483b4499d916822ccc08715f26431e3ca39c599c"],"state_sha256":"fb2290d9f395ddf77937dd5b525439a0e18a632baefe32be450c7954e66b85cc"}
