Static ZZ interaction, which causes a frequency shift of a qubit depending on the state of neighboring qubits, is one of the major obstacles to integrating fixed-frequency transmon qubits. Here we propose and experimentally demonstrate ZZ-interaction-free single-qubit-gate operations on a superconducting transmon qubit by utilizing a semi-analytically optimized pulse based on a perturbative analysis. The gate is designed to be robust against slow qubit-fr","authors_text":"Kentaro Heya, Shuhei Tamate, Shu Watanabe, Yasunobu Nakamura, Yutaka Tabuchi","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-09-25T07:49:27Z","title":"ZZ-Interaction-Free Single-Qubit-Gate Optimization in Superconducting Qubits"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2309.13927","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":"sha256:7cac1645b5bf2b8bae899b7f961de5b4334c3301c4cb9043f97ddd966474e252","target":"record","created_at":"2026-07-05T07:30:21Z","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":"be4061bb741da50182cebcabb420e946d38fc3c50ed57b52807fa03327307e59","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2023-09-25T07:49:27Z","title_canon_sha256":"7ea0aa6fe7541dd6724165b0ed98749e4cfaa7e425f352e237bc062ea77e3dc3"},"schema_version":"1.0","source":{"id":"2309.13927","kind":"arxiv","version":2}},"canonical_sha256":"38980fe9fd06db7e5392ddc20cb21a988a9f38e0d2e2535c474b08a676622f09","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"38980fe9fd06db7e5392ddc20cb21a988a9f38e0d2e2535c474b08a676622f09","first_computed_at":"2026-07-05T07:30:21.172218Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:30:21.172218Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jn15c5MotSi02xpt6O1gT3UQEj7UF+hBZkr/05uAg8f51Mfb8/n1Yth6bFXbnAr7BwCA+/2P1xC7frkup6GoBQ==","signature_status":"signed_v1","signed_at":"2026-07-05T07:30:21.172593Z","signed_message":"canonical_sha256_bytes"},"source_id":"2309.13927","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7cac1645b5bf2b8bae899b7f961de5b4334c3301c4cb9043f97ddd966474e252","sha256:58f92efb9a5e67491e605d753e812512975e03df1dcac4d92aeddc60b2ea27bf"],"state_sha256":"3cc998ca602920e92b7fe8ca0e8b70246686045449649c94f8a7fdfc3c5e8789"}
