When tunneling can be ignored (at high laser intensities), we show that a well-defined qubit can be associated with the states of the atoms trapped in each of the rings. Each of these two-level systems can be manipulated by a suitable configuration of Raman laser beams imprinting a synthetic flux onto each Mexican hat cell of the lattice. Overall, we believe that the system has the potential to form a scalable architecture for atomtronic flu","authors_text":"Beno\\^it Gr\\'emaud, Christian Miniatura, Leong Chuan Kwek, Luigi Amico, Rainer Dumke, Shabnam Safaei","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2016-06-22T10:48:30Z","title":"Two-dimensional network of atomtronic qubits"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1606.06890","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":"sha256:8073b503e51d382504f4137e98a2d7a978b61fd88d34ca8dd9da269d60e5b580","target":"record","created_at":"2026-05-18T00:19:09Z","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":"504b04e3567544d6c8037bbcc7fba38a8ecc9dd9c38c3d73f031f10ee0ef0855","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cond-mat.quant-gas","submitted_at":"2016-06-22T10:48:30Z","title_canon_sha256":"837d3facd8d94652811593b44247a800f7d557bce5858c8838dd9e57df6ee9fd"},"schema_version":"1.0","source":{"id":"1606.06890","kind":"arxiv","version":2}},"canonical_sha256":"560ea86c62183def7dd760b061a20ed811682b35a3c9683e4cbe43d9a1a21592","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"560ea86c62183def7dd760b061a20ed811682b35a3c9683e4cbe43d9a1a21592","first_computed_at":"2026-05-18T00:19:09.158243Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:19:09.158243Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"fqTBqftAA3i6axigfYULDgdA7UR8fXcOvuycXnsHzfKqlnZHmGusqD/43vXtdFwaC7wbsn0lAj2s0hIx0wytCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:19:09.158854Z","signed_message":"canonical_sha256_bytes"},"source_id":"1606.06890","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8073b503e51d382504f4137e98a2d7a978b61fd88d34ca8dd9da269d60e5b580","sha256:82a989206d3f6334cddcf2db2a0c6f7f2a6ee9af478f191f0d49b0da06302d3a"],"state_sha256":"4578610e78c363972f96195e38ad2a57124505749bad46379b9b29e4b5fa9d7c"}
