The gate operations are realized within the two lower flux states of the SQUIDs by using a quantized cavity field and classical microwave pulses. Our scheme is achieved without any type of measurement, does not use the cavity mode as the data bus and only requires a very short resonant interaction of the SQUID-cavity system. As an application of the QCPG operation, we also propose a scheme for generating the cluster states of many SQUIDs","authors_text":"Gang Zhang, Ping Dong, You-Min Yi, Zheng-Yuan Xue, Zhuo-Liang Cao","cross_cats":[],"headline":"","license":"","primary_cat":"quant-ph","submitted_at":"2006-07-06T13:16:21Z","title":"Quantum controlled phase gate and cluster states generation via two superconducting quantum interference devices in a cavity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"quant-ph/0607043","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":"sha256:191d8705e1b7ce2616efebbd0975a7b83e3b569da882090a5569af6b99cf8d36","target":"record","created_at":"2026-05-18T04:08:52Z","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":"94d712353080cb54dd4582c3f0b374f2cc3f36d010eacb0258250ecdd2e4d1c4","cross_cats_sorted":[],"license":"","primary_cat":"quant-ph","submitted_at":"2006-07-06T13:16:21Z","title_canon_sha256":"12a40ce402e8c5f9684f6fee9cfadc290e85324567964bdff66745d945d6a3bc"},"schema_version":"1.0","source":{"id":"quant-ph/0607043","kind":"arxiv","version":1}},"canonical_sha256":"f1982cdad62364b3db2145982c77f6b1894bc5f9dcabe479dc3bc336851b0d55","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"f1982cdad62364b3db2145982c77f6b1894bc5f9dcabe479dc3bc336851b0d55","first_computed_at":"2026-05-18T04:08:52.224011Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:08:52.224011Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KPpJbc3bojyNeCS2BlsxSCGaNpBpf6isiOX6iscUwrADtQXVYUND4W607emLslSU5octfovHsgoW0rkxRSSxBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:08:52.224483Z","signed_message":"canonical_sha256_bytes"},"source_id":"quant-ph/0607043","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:191d8705e1b7ce2616efebbd0975a7b83e3b569da882090a5569af6b99cf8d36","sha256:2699026564a89c5dba3dc5e47ed7340a8bdc48a8da56952450317dd98fb2391f"],"state_sha256":"99d98cf542e25569ca15bebcda520b826bebb3e833de6024e4f1c7ff5e188942"}
