Characterizing Large Scale Quantum Systems with Error Per Circuit Layer
Travis Hurant, Arian Vezvaee, Swarnadeep Majumder +3
Quantum benchmarks provide compact measures of performance that are important for evaluating and comparing quantum systems. Circuit-level benchmarks are particularly valuable becau…
A hardware-safety-gated system for LLM-written native ARTIQ control code on a trapped-ion platform
Duanyang Wang, Lu Qi, Yuanheng Xie +2
Large-language-model (LLM) agents can write and run experimental control code. This allows laboratory work to be conducted autonomously. However, this autonomy raises a safety prob…
Leveraging Correlated Decoding for Bias-Tailored Compass Codes
Arianna Meinking, Julie Campos, Kenneth R. Brown
Quantum error correction (QEC) is often implemented on hardware that experiences biased noise, where dephasing errors occur more frequently than other errors. This has motivated ma…
Sympathetic Cooling in Trapped Ions with Spectral Selectivity via the Zeeman Shift
Kavyashree Ranawat, Jiyong Yu, Andrew Van Horn +3
High-fidelity quantum logic operations in trapped ions often require the ions' collective motion to be cooled to near the ground state. Since cooling the ions' motion typically inv…
Architecting Early Fault Tolerant Neutral Atoms Systems with Quantum Advantage
Sahil Khan, Sayam Sethi, Kaavya Sahay +6
Recent advancements in neutral atom platforms have enabled exploration of early fault-tolerant (FT) architectures for applications with quantum advantage, such as quantum dynamics…
