The chip improves qubit reliability by 1000 times over previous generations, achieving an average qubit lifetime of 20 seconds and instance durations up to 1 minute. Microsoft expects to realize a scalable quantum computer by 2029.","whyItMatters":"The leap in qubit reliability moves topological quantum computing from a theoretical promise toward a practical, scalable system within a defined timeline.","webCardHtml":"\u003cp\u003eMicrosoft announced Majorana 2 on June 2, 2026, a topological quantum chip built with the company's Microsoft Discovery AI agents. The chip uses a lead superconductor instead of the aluminum used in Majorana 1, and its qubits maintain a quantum state 1000 times longer than first-generation qubits. Microsoft described the reliability gain as comparable to a phone battery that dies in one day lasting nearly three years on a single charge. The company said it expects to realize a scalable quantum computer by 2029, which could address problems in health, food supply, sustainability, and energy production.\u003c/p\u003e","blueskyPost":"Microsoft announced Majorana 2, a topological quantum chip with 1000x qubit reliability.
