We recall how to characterize spatial and temporal entanglement in this framework. An operative protocol is presented, to map a history state into the ket of a static composite system. We show, by examples, how the Leggett-Garg and the temporal CHSH inequalities can be violated in our approach.","authors_text":"Anna Gabetti, Leonardo Castellani","cross_cats":["hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2024-05-29T18:10:02Z","title":"Space and time correlations in quantum histories"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2405.19427","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":"sha256:0d20668d13e354c8f28327788aba4a0515f03b1dbea45f19ef6896b44e77a3e6","target":"record","created_at":"2026-07-05T08:25:35Z","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":"3f80e371c9d018517d172237005da89864fde1393073950873635cf0013671af","cross_cats_sorted":["hep-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2024-05-29T18:10:02Z","title_canon_sha256":"91c84c8f42243f28dd1d9bbdec7008eae8a1a67e974e5d6bc0370cb35bcf436a"},"schema_version":"1.0","source":{"id":"2405.19427","kind":"arxiv","version":1}},"canonical_sha256":"7171a6631835353542a2e11c05acfc4eca81b23e826904bc0fa9fc77536300a0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7171a6631835353542a2e11c05acfc4eca81b23e826904bc0fa9fc77536300a0","first_computed_at":"2026-07-05T08:25:35.269433Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T08:25:35.269433Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ezzmz6fM/NVbofkCZHjgkRp9822J1YzCFvb2ZuOY4Vx8KbDx3W9CAlgNKaXpfQQhSb0fX1owfv+NdPl5VZlBBg==","signature_status":"signed_v1","signed_at":"2026-07-05T08:25:35.269830Z","signed_message":"canonical_sha256_bytes"},"source_id":"2405.19427","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0d20668d13e354c8f28327788aba4a0515f03b1dbea45f19ef6896b44e77a3e6","sha256:0e0a48927705f967d62418bcc85f7cdc3323a64e05ed5077f0345d442c3b8c1a"],"state_sha256":"6323ef67993c5d9c66f21743719dc9566d01bba53e13d96d4d2572deed20a900"}
