IonQ demonstrated an end-to-end system that corrects quantum errors in real time without pausing execution. The decoder operates on a standard off-the-shelf CPU and handled benchmark circuits simulating 31.5M quantum operations with an added processing time of 0.02%. IonQ claims the result is the industry's first to achieve this capability on a single processor.

The simulation spanned 408 logical qubits and aligns with the company's Walking Cat architecture and roadmap toward systems controlling thousands of qubits. This approach prevents the need for additional classical hardware as the quantum system expands.
