Atom Computing Demonstrates 90 Rounds of Error Correction in Neutral-Atom Quantum Computer, but Errors Still Accumulate

Atom Computing researchers operated a neutral-atom quantum computer that repeatedly detected and corrected its own errors during extended runs. The system performed up to 90 consecutive rounds of error checking without halting. The team increased the size of qubit groups used for error correction from 16 to 32 qubits.

Error rates fell with the larger grouping, and no additional errors appeared from the scale-up. ” The researchers spread quantum information across multiple qubits so that some serve as an alert system for errors. When an error is flagged, the computation can be discarded and restarted.

@NewScientist reported that similar simultaneous gains in qubit count and error reduction were achieved in 2023 by Google researchers using superconducting circuits and in 2025 by teams at the University of Science and Technology of China and at Harvard University.

” He noted that further reductions in overall error rates and increases in computation speed remain necessary. Mark Saffman at the University of Wisconsin-Madison observed that some additional errors accumulated across the 90 rounds.

Bloom said the group is already addressing those errors and expects continued performance gains. ” Thompson added that he expects rapid progress across the industry.
