In practice, two-qubit entangling gates constitute a dominant error source, limiting circuit depths and performance in fault-tolerant architectures. Using a neutral-atom quantum processor, we realize entangling CZ gates with a high Rabi frequency smooth-amplitude pulse, employing state-selective readout and qubit reuse for fast calibration, and achieve state-of-the-art fidelities of 99.854(4)% which improve to 99.941(3)% upon loss postselection, with stable performance for 10 hours. We then use these low-error gates in quantum circuits with coherent atom rearrangement. We first benchmark performance by creating and disentangling cluster states, and subsequently implement scrambling circuits featuring longer-range connectivity to study non-locally entangled states generated through chaotic dynamics. These results pave the way towards deep-circuit, efficient fault-tolerant quantum computation.","external_url":"https://arxiv.org/abs/2604.25987","cited_by_count":null,"metadata_source":"pith","metadata_fetched_at":"2026-07-09T18:56:27.080842+00:00","pith_arxiv_id":"2604.25987","created_at":"2026-05-11T23:41:18.490302+00:00","updated_at":"2026-07-09T18:56:27.080842+00:00","title_quality_ok":true,"display_title":"High-fidelity entangling gates and nonlocal circuits with neutral atoms","render_title":"High-fidelity entangling gates and nonlocal circuits with neutral atoms"},"hub":{"state":{"work_id":"c215195a-df73-4e1c-ae00-01923c7c0832","tier":"hub","tier_reason":"10+ Pith inbound or 1,000+ external citations","pith_inbound_count":15,"external_cited_by_count":null,"distinct_field_count":2,"first_pith_cited_at":"2026-05-05T16:37:52+00:00","last_pith_cited_at":"2026-07-08T09:01:45+00:00","author_build_status":"not_needed","summary_status":"needed","contexts_status":"needed","graph_status":"needed","ask_index_status":"not_needed","reader_status":"not_needed","recognition_status":"not_needed","updated_at":"2026-08-22T18:59:47.662852+00:00","tier_text":"hub"},"tier":"hub","role_counts":[{"context_role":"background","n":2}],"polarity_counts":[{"context_polarity":"background","n":2}],"runs":{},"summary":{},"graph":{},"authors":[]}}
