Microsoft has unveiled its new Majorana 2 quantum chip, claiming a dramatic improvement in quantum stability that could accelerate the path toward commercially useful quantum computing.
According to the company, the chip achieved a parity lifetime of 20 seconds, representing more than a 1,000-fold increase in stability compared with its predecessor, Majorana 1.
Microsoft said the breakthrough was aided by its Microsoft Discovery artificial intelligence platform, which analyzed nearly two decades of experimental research data.

The AI-guided process reportedly helped scientists identify lead as a more effective superconducting material than aluminum, improving protection for quantum bits, or qubits, from external disturbances.
Zulfi Alam, Microsoft’s corporate vice president for quantum technologies, said the company remains on track to develop a quantum machine capable of solving commercially relevant problems by 2029.
The announcement comes amid intensifying competition in the quantum computing sector, with IBM, Google, and Amazon pursuing their own advanced systems.
However, some experts remain cautious. Physicist Henry Legg of the University of St Andrews noted that Microsoft’s findings have not yet undergone peer review and argued that key scientific questions remain unresolved.
Microsoft said certain technical details remain confidential due to commercial considerations as it continues collaborating with the U.S. Defense Advanced Research Projects Agency on utility-scale quantum computing research.
