Some particular instances are analysed and parallel transport leading to the off-diagonal mixed state geometric phase is delineated. A complete experimental realisation of the off-diagonal mixed state geometric phases in the qubit case using polarisation-entangled two-photon interferometry is proposed.","authors_text":"Erik Sj\\\"oqvist, Stefan Filipp","cross_cats":[],"headline":"","license":"","primary_cat":"quant-ph","submitted_at":"2002-12-19T09:02:56Z","title":"Off-diagonal mixed state phases in unitary evolution"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"quant-ph/0212111","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":"sha256:4bd9b5e1ff7a6bbe0e253fe114504e9fcbf4b7206db961f656597491da1e9deb","target":"record","created_at":"2026-05-18T01:08:59Z","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":"e824a52a63fc77e41ca03cd12e8e2501d099a7b20cf420b5992a0b04f68059aa","cross_cats_sorted":[],"license":"","primary_cat":"quant-ph","submitted_at":"2002-12-19T09:02:56Z","title_canon_sha256":"642a85e4d1b55208915601322a60757b85ff131948e49c8ae10d7dbed6ac3589"},"schema_version":"1.0","source":{"id":"quant-ph/0212111","kind":"arxiv","version":1}},"canonical_sha256":"62ea225c0f0ddf68fb4b16880244b172a2c3ef8b796e7cd10873abc2d44683de","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"62ea225c0f0ddf68fb4b16880244b172a2c3ef8b796e7cd10873abc2d44683de","first_computed_at":"2026-05-18T01:08:59.408220Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:08:59.408220Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3/zFQaHa3+sXhmKtfBON0wZdezFgX0onvFEt2GVD4ej3+ilia66680p+T3PwJTBu6T0w9KvcYBzwY9PguVnbDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:08:59.408659Z","signed_message":"canonical_sha256_bytes"},"source_id":"quant-ph/0212111","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4bd9b5e1ff7a6bbe0e253fe114504e9fcbf4b7206db961f656597491da1e9deb","sha256:d00acb1b3c0fa5ef6c3fde64fcb2604aab6394c5e40647d9d83b71cf7ca3736d"],"state_sha256":"88ce09344726d134cad60179ee23140aced4d72d7e46e079c7971dca23a8c2e9"}
