Microsoft's Majorana 2 chip 1000x more reliable, timeline cut to 2029

Microsoft's Majorana 2 quantum chip has 1000 times more reliable qubits than its first Majorana version. The reliability boost reduced Microsoft's scalable quantum computer timeline from 2033 to 2029. The improvement was achieved using agentic AI to optimize qubit stability. This shift halves the original target date for a scalable quantum computer. The change enables faster progress toward practical quantum computing applications. Microsoft has not disclosed specific qubit count or error rates for Majorana 2.
