A topological quantum chip is designed with the company's own agent

Microsoft’s announcement describes Majorana 2 as a next-generation topological chip on a new materials stack, developed with the aid of Microsoft Discovery’s agentic AI, with a 1,000-fold gain in qubit reliability over the prior generation and a scalable-quantum target pulled forward to 2029, roughly halving the original timeline (Microsoft). The newsletter reads it as Microsoft hunting cheaper compute at the physics layer, in the same breath as the borrowed silicon and borrowed money of the TPU credit deal. In the silicon-designs-itself line it follows a CPU taken to tape-out in twelve hours and a model topping the leaderboard for the kernels it runs on, and lands a week after imec patterned a qubit with production EUV; the quantum thread continues with a chip that learns from its own errors mid-run in July.
