aiqbench analysis
This study introduces scalable benchmarking protocols using QAA and QAOA to evaluate neutral atom quantum processors on maximal independent set problems up to 102 qubits. By comparing systems like QuEra Aquila and Pasqal Fresnel, the work establishes an application-level figure of merit that directly links hardware improvements to solution quality without isolating specific noise sources. These methods provide a standardized reference for tracking progress in neutral atom quantum computing as processors scale toward fault-tolerant regimes.
Benchmarking neutral atom-based quantum processors at scale
arXiv:2511.22967v2 Announce Type: replace Abstract: In recent years, neutral atom-based quantum computation has been established as a competing alternative for the realization of fault-tolerant quantum computation. However, as with other quantum technologies, various sources of noise limit their performance. With processors continuing to scale up, new techniques are needed to characterize and compare them in order to track their progress. In this work, we present two systematic benchmarks that evaluate these quantum processors at scale. We use the quantum adiabatic algorithm (QAA) and the quantum approximate optimization algorithm (QAOA) to solve maximal independent set (MIS) instances of random unit-disk graphs. These benchmarks are scalable, relying not on prior knowledge of the system's evolution but on the quality of the MIS solutions obtained. Rather than isolating individual sources of noise, they provide an application-level figure of merit: improvements in a QPU and its implementation of the protocols should be reflected in higher-quality MIS solutions. We benchmark quera_aquila and pasqal_fresnel on problem sizes up to 102 and 85 qubits, respectively. Overall, quera_aquila performs better on QAOA and QAA instances. Finally, we generate MIS instances of up to 1000 qubits, providing scalable benchmarks for evaluating future, larger processors as they become available. The proposed protocols can therefore serve as a common reference for comparisons, allowing future work to assess whether advances in hardware translate into measurable improvements in MIS solution quality.
