Neutral-atom quantum computer demonstrates repeated error correction

A neutral-atom quantum computer corrected its own errors across repeated computation cycles, researchers reported. The system scaled error-correction groups from 16 to 32 qubits and maintained lower error rates at the larger size. Error correction spreads data across multiple qubits so that some can detect and flag mistakes.

The machine used these alert qubits to identify errors and restart affected calculations.

Scaling and endurance tests The team ran the machine through 90 successive rounds of error monitoring while keeping the system active. Error rates remained stable or declined as the qubit groups grew. Prior experiments at other institutions had shown similar scaling in superconducting and neutral-atom systems, but the new test combined scaling with continuous operation.

Remaining technical limits Some additional errors still accumulated over the 90 rounds. Researchers stated they are already addressing those sources and expect further reductions in overall error rates. The work adds neutral-atom systems to the short list of platforms that have demonstrated both increased qubit counts and sustained error correction in a single experiment.
