Microsoft’s Majorana 2 promises 1,000x reliability, edging quantum era forward

Microsoft unveiled Majorana 2, a topological quantum chip the company says is 1,000 times more reliable than Majorana 1, with qubits lasting up to a minute. AI-driven research and manufacturing acceleration helped speed development, pushing toward scalable quantum computing by 2029. The story also notes rising crypto concerns, as advances in quantum tech threaten Bitcoin’s cryptography and Citi warns practical quantum attacks could arrive sooner than expected.
