Microsoft Quantum Computing Claim Still Lacks Evidence

Nature: A Microsoft researcher [this week] presented results behind the company's controversial claim last month to have created the first 'topological' qubits -- a long-sought goal of quantum computing. In front of a packed room at a meeting of the American Physical Society (APS), Chetan Nayak, a theoretical physicist leading Microsoft's quantum computing effort in Redmond, Washington, explained how the company is developing topological qubits, which would be the building blocks for a noise-res
