Sandia National Laboratory and Quantinuum have published a peer-reviewed paper with the results of testing the 98-cubic quantum computer Helios. The system, built on barium ions with QCCD architecture and full cubit binding, demonstrated record accuracy: 99.9975% for single-cubit and 99.921% for double-cubit operations. During the Random Circuit Sampling (RCS) run, Helios showed results that far exceeded classical simulation capabilities.

Sandia’s specialists have certified the processor’s performance by applying measurement techniques in the middle of the circuit, which is crucial for correcting quantum errors. Co-author of the study, Robin Blum-Kohut, emphasized that for modern quantum systems reliability is more important than speed.

Helios was launched at the end of 2025 and is already available to corporate customers, including Amgen, BMW Group, JPMorganChase, and SoftBank, via a cloud service and in local deployment format.
