Nature Publishes Peer-Reviewed Critique of Microsoft Quantum Claims
The Nature commentary, peer-reviewed, directly challenges the validity of Microsoft's 2025 topological qubit announcement, a claim that had already drawn skepticism from physicists.

Nature has published a peer-reviewed commentary by Dr. Henry Legg of the University of St Andrews questioning Microsoft's 2025 quantum computer technology. Legg points to Python data processing errors, arbitrary data selection, and inconsistent results in Microsoft's topological gap detection paper. Microsoft has published a rebuttal in Nature defending its research.
Dr. Henry Legg's commentary, published in Nature, identifies two specific technical problems with Microsoft's 2025 paper. First, Microsoft's graphing code displayed only the largest region meeting conditions, excluding other qualifying regions, which Legg says made results appear more favorable. Second, the Python data processing code inverted some data based on array position rather than actual voltage values, potentially misinterpreting measurements. Legg also notes that broader data not included in the original paper showed random noise rather than clear gaps, suggesting device disturbances that may undermine the claimed state. Microsoft responded with a rebuttal in the same journal, calling the code issues minor and arguing they did not properly consider the measurement results.
