A five-star bake. Worth schmearing, sharing, saving.
Summary
Microsoft has unveiled its Majorana 2 topological quantum chip, achieving a 1,000x improvement in qubit reliability over the previous Majorana 1 chip. This breakthrough has allowed the company to dramatically accelerate its commercial quantum computing timeline from 2035 to 2029. The advancement was enabled in part by agentic AI, which helped overcome the qubit reliability barrier that has long plagued quantum computing development.
