A quantum processor learns from its own errors mid-run

Google’s Willow processor now adjusts to its own quantum errors while a computation is running rather than after it (Google Research), the first time the corpus records a substrate correcting itself mid-run rather than being redesigned between generations. It carries the silicon-designs-itself line, Microsoft’s Majorana 2 designed with its own agent and Princeton’s diffusion-drawn RF circuits, down into the run itself, four months after Google opened Willow to early access. In the same breath Musk pitched Megapods, containerized AI compute to be dropped wherever power already exists, counting Tesla’s seven gigawatts of Superchargers as a site inventory (thread); the issue sets the self-correcting substrate beside the capital stack it draws on, the same day Google posted its first-ever quarterly cash burn.
