Microsoft Announces Majorana 2 Quantum Chip With 1000x Qubit Reliability

Microsoft has announced the next-generation topological quantum chip Majorana 2, developed using its Microsoft Discovery AI agents. 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.

Microsoft 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.
