Nature Study Characterizes Quantinuum's 98-Qubit Helios
The trapped-ion processor combines all-to-all connectivity with an average two-qubit gate infidelity of 7.9 × 10^-4 across operating zones.

A Nature study characterizes Helios, Quantinuum's 98- trapped-ion quantum charge-coupled-device processor, combining its qubit count with measurements of control quality. More qubits are useful for demanding circuits only when the processor also maintains sufficiently strong connectivity and control.
The paper reports all-to-all connectivity and an average two-qubit gate infidelity of 7.9(2) × 10^-4 across operating zones.
That average does not describe the error rate of every gate or a complete algorithm. The paper's publication record also includes a July 7 publisher correction. Application-level results would need circuit depth, runtime and full output accuracy alongside these component benchmarks to show how the processor performs on complete computations.
