Among different hardware approaches, trapped-ion quantum processors are a leading technology for quantum computing, with established high-fidelity operations and architectures with promising scaling. Here, we demonstrate and thoroughly benchmark the IonQ Forte system: configured as a single-chain 30-qubit trapped-ion quantum computer with all-to-all operations. We assess the performance of our quantum computer operation at the component level via direct randomized benchmarking (DRB) across all 30 choose 2 = 435 gate pairs. We then show the results of application-oriented \\cite{IonQ_AQ20_2022}\\cite{qedcPeerReviewed} benchmarks and show that the system passes the suite of algorithmic qubit (AQ) benchmarks up to #AQ 29. Finally, we use our component-level benchmarking to build a system-level model to predict the application benchmarking data through direct simulation. While we find that the system-level model correlates with the experiment in predicting application circuit performance, we note quantitative discrepancies indicating significant out-of-model errors, leading to higher predicted performance than what is observed. This highlights that as quantum computers move toward larger and higher-quality devices, characterization becomes more challenging, suggesting future work required to push performance further.<\/jats:p>","DOI":"10.22331\/q-2024-11-07-1516","type":"journal-article","created":{"date-parts":[[2024,11,7]],"date-time":"2024-11-07T14:23:25Z","timestamp":1730989405000},"page":"1516","update-policy":"https:\/\/doi.org\/10.22331\/q-crossmark-policy-page","source":"Crossref","is-referenced-by-count":95,"title":["Benchmarking a trapped-ion quantum computer with 30 qubits"],"prefix":"10.22331","volume":"8","author":[{"given":"Jwo-Sy","family":"Chen","sequence":"first","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik","family":"Nielsen","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthew","family":"Ebert","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Volkan","family":"Inlek","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenneth","family":"Wright","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vandiver","family":"Chaplin","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrii","family":"Maksymov","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduardo","family":"P\u00e1ez","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amrit","family":"Poudel","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Maunz","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John","family":"Gamble","sequence":"additional","affiliation":[{"name":"IonQ, College Park, MD 20740"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"9598","published-online":{"date-parts":[[2024,11,7]]},"reference":[{"key":"0","doi-asserted-by":"publisher","unstructured":"Youngseok Kim, Andrew Eddins, Sajant Anand, Ken Xuan Wei, Ewout Van Den Berg, Sami Rosenblatt, Hasan Nayfeh, Yantao Wu, Michael Zaletel, Kristan Temme, et al. ``Evidence for the utility of quantum computing before fault tolerance&apos;&apos;.
