Microsoft unveils Majorana 2 quantum chip with 1000x reliability gain via agentic AI (news.microsoft.com)

• Majorana 2: topological quantum chip with 1000x qubit reliability improvement
• Mean qubit lifetime of 20 seconds, peaks up to one minute
• Microsoft targets scalable quantum computer by 2029
• Microsoft Discovery platform and app now generally available

"Microsoft has introduced Majorana 2, its next-generation topological quantum chip, developed using Microsoft Discovery's agentic AI. The chip achieves a 1000-fold improvement in qubit reliability over the previous generation, with a mean qubit lifetime of 20 seconds and instances lasting up to one minute. Microsoft now expects a scalable quantum computer by 2029, halving its original timeline. Microsoft Discovery is now generally available."
