A recent commentary article in Nature raises doubts about Microsoft's major breakthrough in quantum computing announced last year, which forms the basis for Microsoft's plan to launch a functional quantum computing system by 2029. Microsoft has been committed to exploring new quantum technology pathways in hopes of achieving a leapfrog advantage, but its related scientific achievements have long been questioned by the academic community, with previously funded papers having been retracted or flagged for doubts. This time, the question (questioning) focuses on Microsoft's core paper published in February 2025, which claims to have developed software capable of identifying subtle energy gaps in highly conductive wires, crucial for manufacturing stable qubits. However, skeptics point out inconsistencies and data fabrication in the software results, noting that the publicly available dataset only shows random noise without evidence of energy gaps, even likening the research to searching for a 'Jesus toast' in random noise. Microsoft responded by stating that the software is a practical debugging tool, maintaining its research conclusions and asserting that practical progress has been made in its quantum projects. Nayak, in charge of hardware development, refute (rebutted) by comparing it to 'seeing the plane right in front of you.' Other physicists have criticized Microsoft's technological approach as lacking empirical evidence, while the paths adopted by manufacturers like IBM are supported by solid experimental evidence.
