We present a compound photonic-atomic quantum computing platform that uses cavity QED to realize near-deterministic entangling operations between flying photonic qubits and stationary atomic qubits. Photons provide long-range connectivity and scalability via measurement-based quantum computing (MBQC), while atoms supply reusable, near-deterministic resources for photon generation and entanglement, overcoming the inefficiency of p","authors_text":"Alexander Poddubny, Aviad Landau, Barak Dayan, Dana Ben Porath, Daniel Azses, David Dentelski, Doron Azoury, Geva Arwas, Konstantin Yavilberg, Michael Slutsky, Nadav Kandel, Orel Bechler, Yair Margalit, Yaron Jarach","cross_cats":["physics.atom-ph"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-06-29T14:40:27Z","title":"Blueprint for a fault-tolerant compound photon-atom quantum architecture"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.30385","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":"sha256:43144da9399e31aa4dd7513e8dd87923e635b5f96780c2d764842399e990517d","target":"record","created_at":"2026-06-30T02:18:12Z","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":"6c56c6bf5da564dfac03213b2f77df1d5388833475a94fc8f805f8c2c8a5507d","cross_cats_sorted":["physics.atom-ph"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2026-06-29T14:40:27Z","title_canon_sha256":"ea9da4fabaa775b34ba06f15cbc7148c0f9158f1ce15bd493298f1a35e0d049e"},"schema_version":"1.0","source":{"id":"2606.30385","kind":"arxiv","version":1}},"canonical_sha256":"2ff628b4b42aa1abd25710df03028736773c34cb1a7bcc5760ddf54a6caf14dc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2ff628b4b42aa1abd25710df03028736773c34cb1a7bcc5760ddf54a6caf14dc","first_computed_at":"2026-06-30T02:18:12.881793Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-30T02:18:12.881793Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZRMPOazfo1hA4zfSsYBQajBclDcFq5lL23rMgl0qVoZPzFxalw9Nhzd/jeMoXZ2auvAbm87s6/GrInqMYHjSDQ==","signature_status":"signed_v1","signed_at":"2026-06-30T02:18:12.882249Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.30385","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:43144da9399e31aa4dd7513e8dd87923e635b5f96780c2d764842399e990517d","sha256:760d5643f80bb166322fa22bd38248b51413bfaef0d16209591052878cbfb0fe"],"state_sha256":"569d3769663b213e5f6d011c41dd6c86c15e10e89dd322bb787881f4ff0b95d0"}
