A critique published successful Nature Wednesday calls the basal exertion down Microsoft's "breakthrough" quantum computing spot the Majorana 1 into question. Microsoft unveiled the spot successful February 2025 and said it featured a brand-new exertion known arsenic a topological qubit. Topological qubits, they said, would beryllium the "building blocks" for their aboriginal quantum computer. Microsoft announced the adjacent procreation spot Majorana 2 astatine Build earlier this month.

But successful a peer-reviewed article, Henry Legg, a physicist astatine the University of St. Andrews, re-analyzed Microsoft's information connected their instrumentality and argued that the company's researchers did not conclu …
