Trapped-ion systems excel in small-scale operations and support rapid qubit scaling via long-chain architectures. However, their performance in larger systems is hindered by spectral crowding in radial motional modes, a problem that forces reliance on intricate pulse-shaping techniques to maintain gate fidelities. Here, we overcome this challenge by developing a novel trapped-ion processor with an individual-addressing system that generates steerable He","authors_text":"Junhua Zhang, Liyun Zhang, Qinyang Yu, Xueying Mai, Yao Lu","cross_cats":["physics.atom-ph","physics.optics"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-06-24T11:45:28Z","title":"Scalable entangling gates on ion qubits via structured light addressing"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.19535","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":"sha256:96784687f96e3b9e52b57d6315bdae795637b23a614558756fa7d955b54f9141","target":"record","created_at":"2026-07-05T11:26:34Z","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":"52f2e4620bed611a11fc06e553fe02c6804b34198098dd7883e6007655c5d8f4","cross_cats_sorted":["physics.atom-ph","physics.optics"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-06-24T11:45:28Z","title_canon_sha256":"3aa1f3e54a22b25cebc401536bf3ebd943152c20cb728bcb0276d436c8755c30"},"schema_version":"1.0","source":{"id":"2506.19535","kind":"arxiv","version":1}},"canonical_sha256":"fffbdede324818ebe2a299728092ba62e159c10305f0cfcf1ca3103e7eb49d5c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fffbdede324818ebe2a299728092ba62e159c10305f0cfcf1ca3103e7eb49d5c","first_computed_at":"2026-07-05T11:26:34.165009Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:26:34.165009Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"b7OIFl0kA6I5x+SePJIT1Wz9lNdtiR01Mg7pkeLEzNusCBDisRsjv/IZ1GRlWziO2TFp4o6Qq+uRIvdZfETDAg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:26:34.165498Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.19535","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:96784687f96e3b9e52b57d6315bdae795637b23a614558756fa7d955b54f9141","sha256:1ae2ab9bc50e89f44ff480d382e28cec19b6c1b88dc7afd7a343fefefbac928a"],"state_sha256":"fd410c47a4991599ff9d5cb779b2034e838b58ecd94168912967ec399e6504f1"}
