Recent experimental advances include the time-dependent local control of chemical potentials and tunnelings, and thus enable to operate this platform digitally as a programmable quantum simulator. Here, we explore these opportunities and develop ground-state preparation algorithms for different fermionic models, based on the ability to implement both single-particle and many-body, high-fidelity fermionic gates, as provide","authors_text":"Alejandro Gonz\\'alez-Tudela, Christian Kokail, Cristian Tabares, Daniel Gonz\\'alez-Cuadra, Peter Zoller","cross_cats":["cond-mat.quant-gas","cond-mat.str-el"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-02-07T16:40:58Z","title":"Programming optical-lattice Fermi-Hubbard quantum simulators"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.05067","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":"sha256:98dd12822ae6a1ae45f345f6fee86a8978b87833881cd745ea98ce4ae3fbf94a","target":"record","created_at":"2026-07-05T10:11:02Z","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":"ac0b1d324d29e47af0bbd8bd43467ef6289bed7f65d12891154c45d058ebb42d","cross_cats_sorted":["cond-mat.quant-gas","cond-mat.str-el"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"quant-ph","submitted_at":"2025-02-07T16:40:58Z","title_canon_sha256":"5b49c6a86d4eb299ed8cc2855d9a67822bdf715dcaba45e977b5baf53440684b"},"schema_version":"1.0","source":{"id":"2502.05067","kind":"arxiv","version":1}},"canonical_sha256":"7f72c07419c6b5514bb3378b24e74c3459b137691705d87d8f8a24f790213cd7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7f72c07419c6b5514bb3378b24e74c3459b137691705d87d8f8a24f790213cd7","first_computed_at":"2026-07-05T10:11:02.664734Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:11:02.664734Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fDhG3cgHum81ulHWBOrrWIPJyYREf2+HYJPaes9lmc+b8NgIA7xQK4Rs4/a82pQ6GO5EuoXZJcPvXDZa/WwUCQ==","signature_status":"signed_v1","signed_at":"2026-07-05T10:11:02.665310Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.05067","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:98dd12822ae6a1ae45f345f6fee86a8978b87833881cd745ea98ce4ae3fbf94a","sha256:5b3817625c1266d4274c68219f11c4da9677a83630ca95957cdec37a0457bfda"],"state_sha256":"b0ec3fd524d62c5c9906bee7624f14d3130ead9b8b99382d37ba364db8b5c71b"}
