Microsoft announced last year that it had developed a A major breakthrough in quantum computing and Majorana 1, the company’s first quantum processor. When the scientists were he immediately doubts on Microsoft’s statement, the software giant is announcing Majorana 2 today, the next generation of its topological quantum device.
Majorana 2 contains qubits, a unit of information in quantum computing similar to the bits used in computers today, which are 1,000 times more reliable, according to Microsoft. It is the most important factor that helps make quantum computing reliable, thanks to the use of a new stack and support from Microsoft Discovery’s agetic AI.
“To build Majorana 2, the Microsoft Quantum team modified many of the features of Majorana 1 to create more.
stable topological phase,” explains Chetan Nayak, Microsoft’s chief technology officer and corporate vice president of quantum hardware.
The improved hardware means better performance for the qubits, according to Microsoft. “In aluminum from Majorana 1, the lifetime of a qubit was between one and 12 milliseconds, while in Majorana 2, the lifetime exceeds 20 seconds, representing an improvement of more than 1,000x,” says Nayak. Some qubit lifetimes now exceed one minute, enough to convince Microsoft that it has advanced enough to promise the technology it needs in the near future.
“Based on these rapid advances, we are accelerating our path to a scalable, efficient computer,” says Nayak. “We have cut our timeline in half and want to achieve this goal by 2029.” Microsoft is working to develop a fault-tolerant computer based on topological qubits, with the goal of quantum computing to solve some of the world’s most difficult problems.
Microsoft is now releasing Discovery, the platform that helped develop Majorana chips, to its customers today. Microsoft Discovery is designed to facilitate the use of workflows in research and development. A version of the native Microsoft Discovery app now available on GitHuband researchers can use a GitHub Copilot account to access it.
