Majorana 2, made more reliable with Microsoft Discovery agentic AI
Microsoft has introduced Majorana 2, a next-generation topological quantum chip that boasts a 1,000-fold improvement in reliability over its predecessor. This advancement is attributed to the integration of Microsoft Discovery's agentic AI, which aids in scientific discovery. The company aims to achieve a scalable quantum computer by 2029, significantly reducing its original timeline.
- ▪Majorana 2 features a new materials stack that enhances qubit reliability to a mean lifetime of 20 seconds.
- ▪The chip's qubits can maintain their quantum state significantly longer than previous generations, with some instances lasting up to one minute.
- ▪Microsoft Discovery is now generally available, allowing users to deploy AI agent teams for scientific research.
