The KPO can stabilize two coherent states with opposite phases, yielding a quantum superposition called a Schr\\\"{o}dinger cat state. Universal quantum computing with KPOs requires three kinds of quantum gates: $R_z, R_x$, and $R_{zz}$ gates. We theoretically propose a two-qubit gate $R_{zz}$ for highly detuned KPOs. In the proposed scheme, we add another two-photon drive for the first KPO. This leads to the $R_{zz}$ gate based on the driving of the second KPO dependin","authors_text":"Hayato Goto, Hiroomi Chono, Taro Kanao","cross_cats":["cond-mat.supr-con","physics.app-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2022-04-07T10:40:13Z","title":"Two-qubit gate using conditional driving for highly detuned Kerr-nonlinear parametric oscillators"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2204.03347","kind":"arxiv","version":2},"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":"sha256:0f6ea9ee4aa148f214985e5daabc8ab1f93d4ee5496071fb483dd6a51dab50f3","target":"record","created_at":"2026-07-05T05:12:28Z","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":"5a358fd05e512afc9129f25c314bdbe0738aca0997c8308b06af04b8dab9e89e","cross_cats_sorted":["cond-mat.supr-con","physics.app-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2022-04-07T10:40:13Z","title_canon_sha256":"c20f2573c5d222dee06ca48cd7fa45ecaac5581acf3bedda7de533c02b21d62b"},"schema_version":"1.0","source":{"id":"2204.03347","kind":"arxiv","version":2}},"canonical_sha256":"102d01a11a69a52916c63e56efc6bf9b88b171f5195426613aa22997fa63b7a2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"102d01a11a69a52916c63e56efc6bf9b88b171f5195426613aa22997fa63b7a2","first_computed_at":"2026-07-05T05:12:28.315243Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:12:28.315243Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"sqjQW1avhhbsG80+jeXIaueOI9K6oBDQAyy7wTJ8Omlj+qmoF4e4VoHz484bptddqL/Y8Ww68V93jyLzSyoQCA==","signature_status":"signed_v1","signed_at":"2026-07-05T05:12:28.315822Z","signed_message":"canonical_sha256_bytes"},"source_id":"2204.03347","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:0f6ea9ee4aa148f214985e5daabc8ab1f93d4ee5496071fb483dd6a51dab50f3","sha256:a0f9c6b58117f2eeb5400b0683566d5afd04127f5822560db8c57f0acf5537aa"],"state_sha256":"29e18e10cdec2710b84d83bf9099051a08f0939e3707fb9aeb8f3a5e835f865c"}
