They cannot, however, be used for super-luminal signalling. It is also known that it is possible to write down sets of ``super-quantum'' correlations that are more non-local than is allowed by quantum mechanics, yet are still non-signalling. Viewed as an information theoretic resource, super-quantum correlations are very powerful at reducing the amount of communication needed for distributed computationa","authors_text":"David Roberts, Jonathan Barrett, Noah Linden, Sandu Popescu, Serge Massar, Stefano Pironio","cross_cats":[],"headline":"","license":"","primary_cat":"quant-ph","submitted_at":"2004-04-16T14:19:54Z","title":"Non-local correlations as an information theoretic resource"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"quant-ph/0404097","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":"sha256:9bafd2a46f2109b118336ed3e04223b56f3bb0d15fc77af913d434063f37fc03","target":"record","created_at":"2026-07-04T15:05:03Z","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":"7965953607a6f5c4c28b6a11995215a7d808aea96740b91662e116c7fdba7b86","cross_cats_sorted":[],"license":"","primary_cat":"quant-ph","submitted_at":"2004-04-16T14:19:54Z","title_canon_sha256":"314e7a359a3bb5ca246546adb4f45d8722d01a5014f0be7e0d415f1ab31b5958"},"schema_version":"1.0","source":{"id":"quant-ph/0404097","kind":"arxiv","version":1}},"canonical_sha256":"95222e4345daeead13959fa19b5104a6ac403bf9a9cf5ed0b7e34d35f7e63981","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95222e4345daeead13959fa19b5104a6ac403bf9a9cf5ed0b7e34d35f7e63981","first_computed_at":"2026-07-04T15:05:03.585596Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:05:03.585596Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KmqZ0N4DPwHsPlPYFG3+IwjVnxfs3hB/jKY2N4c9XzzZbN6iO68FP4Gi8WMq3Ieuuko49QXTIq2aQTpEXkssAQ==","signature_status":"signed_v1","signed_at":"2026-07-04T15:05:03.586014Z","signed_message":"canonical_sha256_bytes"},"source_id":"quant-ph/0404097","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9bafd2a46f2109b118336ed3e04223b56f3bb0d15fc77af913d434063f37fc03","sha256:cea7059a376ac4cb2c3979e9b6c9f9569da8f998eb1de4ac6783c588ef80de57"],"state_sha256":"fa0640e53e4b2f369371efba40d36857d8632a4e81dd25d33192626f30607fc0"}
