However, to date, only disordered arrays have been demonstrated, due to the non-deterministic loading of the traps. Here, we demonstrate the preparation of fully loaded, two-dimensional arrays of up to 50 microtraps each containing a single atom, and arranged in arbitrary geometries. Starting from initially larger, half-filled matrices of randomly loaded traps, we obtain user-defined target arrays at unit filling. This is achieved with a real-time contro","authors_text":"Antoine Browaeys, Daniel Barredo, Sylvain de L\\'es\\'eleuc, Thierry Lahaye, Vincent Lienhard","cross_cats":["cond-mat.quant-gas","physics.atom-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-07-11T17:19:44Z","title":"An atom-by-atom assembler of defect-free arbitrary 2d atomic arrays"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.03042","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":"sha256:8f7cee8b766a06a153bea0a3fcd4146c22bddf44e3f764d0b1e412ce3b8fdb11","target":"record","created_at":"2026-05-18T00:53:45Z","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":"7d3d4458795338a39f904847ba77ada7b25194e34d63dc8c9cd4e0e7abbdc007","cross_cats_sorted":["cond-mat.quant-gas","physics.atom-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"quant-ph","submitted_at":"2016-07-11T17:19:44Z","title_canon_sha256":"63a94d8286a96060827e629709bb67a7dd079fdea3fe756daeb724ec5ff20def"},"schema_version":"1.0","source":{"id":"1607.03042","kind":"arxiv","version":1}},"canonical_sha256":"9c543ee68029bdbe0fd4d5511eba59f7b74e51996ec62701314354a654ef0d23","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c543ee68029bdbe0fd4d5511eba59f7b74e51996ec62701314354a654ef0d23","first_computed_at":"2026-05-18T00:53:45.253661Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:53:45.253661Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"zxhJAGsmyMfWes2K/DhzD8Et8NH/RuKnpjdg9VFlPAXjSxYCohvVW5XeSGFwcIKY9w+g0T3DL5wCu7n0IL9VDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:53:45.254198Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.03042","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8f7cee8b766a06a153bea0a3fcd4146c22bddf44e3f764d0b1e412ce3b8fdb11","sha256:e9e179c8ac65843049a9a5e23f6a663155b416392d5eabcd54626575e55e31c4"],"state_sha256":"957442d16df9be05c213d201ab3af4616574cdea5ec003847ed578c11268427b"}
