For this purpose, we utilize the codes' description in terms of stabilizers in order to calculate general efficiencies for the loss-free case, but also for specific cases including photon loss. These efficiencies can be, for instance, used for obtaining transmission rates of all-optical quantum repeaters. In the loss-free case, we demonstrate that the im","authors_text":"Frank Schmidt, Peter van Loock","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-12-21T17:38:02Z","title":"Efficiencies of logical Bell measurements on CSS codes with static linear optics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.09278","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":"sha256:29e73fc04fbf4c4cc389beea3ce1d6683ee6bd24f3f8a9478145b78297597201","target":"record","created_at":"2026-05-17T23:43:03Z","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":"297736b72416a143961184744cb6485fc62342d0d2aa81ecce959aa4f1c99b20","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2018-12-21T17:38:02Z","title_canon_sha256":"68daf72eb865018ca06df50ec3dac29bde692afc9459daa9daec635536fe9340"},"schema_version":"1.0","source":{"id":"1812.09278","kind":"arxiv","version":1}},"canonical_sha256":"bf3fc4c5b0ebf7a98ed16369a4c3c2f1a426f0e2f3fac14d807c4c71cf008211","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bf3fc4c5b0ebf7a98ed16369a4c3c2f1a426f0e2f3fac14d807c4c71cf008211","first_computed_at":"2026-05-17T23:43:03.975806Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:43:03.975806Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"8eoO96SOnWHgn4OuFOr1OJSqjnP+VQ/vNvwGRhU4TuqUJPRPOf5B/x920GBKquaoJMKdqQmOOeZ9eEplvWu6Dg==","signature_status":"signed_v1","signed_at":"2026-05-17T23:43:03.976303Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.09278","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:29e73fc04fbf4c4cc389beea3ce1d6683ee6bd24f3f8a9478145b78297597201","sha256:6b4cfc6b9685eb93d301493b56e8c5e17d2d3623c656fc4ef4f03cd6898deb57"],"state_sha256":"c1a083ad871af7cafd29d122d0e90ada901257acda5dfd3b643ceb9084d74a09"}
