Here we propose and analyze an alternative route to a fast $\\sqrt{\\mathrm{SWAP}}$ gate for two fermionic atoms in an optical superlattice based on optimized, time-dependent control of the short and long lattice depths. The gate is implemented by transiently releasing the atoms into a quasi-harmonic confinement centered between the two sites. With an appropriately chosen contact interaction strength, a controlled collision accumulates the exchange ph","authors_text":"Jonathan Nemirovsky, Rafi Weill, Yoav Sagi","cross_cats":["physics.atom-ph","quant-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2025-12-27T11:58:44Z","title":"Fast collisional $\\sqrt{\\mathrm{SWAP}}$ gate for fermionic atoms in an optical superlattice"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2512.22569","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":"sha256:96a3bef1230f0b0be34c8c02f70d316dfbe9bc751e514d037664b9a7247b29d4","target":"record","created_at":"2026-06-10T01:10:58Z","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":"7fc84697c85cb4a6f87c69a381c5ee742e7c3fa5e7fd65ba604dc75419db6da9","cross_cats_sorted":["physics.atom-ph","quant-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2025-12-27T11:58:44Z","title_canon_sha256":"4715c18b45df20abd7e9f840fd8e49e4aa9e695118ce980e4e4dbc49a5e523b3"},"schema_version":"1.0","source":{"id":"2512.22569","kind":"arxiv","version":2}},"canonical_sha256":"4b8ad4e96e69253d4bc2be3aa54d24ab596ce111f9bec86cb3419261988d3933","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4b8ad4e96e69253d4bc2be3aa54d24ab596ce111f9bec86cb3419261988d3933","first_computed_at":"2026-06-10T01:10:58.386144Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-10T01:10:58.386144Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"grD2f3XOVrOXXkK9Q126BkfELORWvMJEJPeWkaFHFPJh4R+T1NY6oBIuHbOhUoeu4VyOtX94KYYP938jbDaIBA==","signature_status":"signed_v1","signed_at":"2026-06-10T01:10:58.387178Z","signed_message":"canonical_sha256_bytes"},"source_id":"2512.22569","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:96a3bef1230f0b0be34c8c02f70d316dfbe9bc751e514d037664b9a7247b29d4","sha256:73f30b2c0b2d4a5f7adb4d3adbcb454ea5ea4653b17a25bb7fc45d122e3fd42a"],"state_sha256":"fe4ce5da53be238fea8894ae45d65ec61814b21d0072d59b10cee004e503e0fb"}
