Willow Chip Cuts Magic-State Errors 40-Fold, Reshaping Quantum Economics
Google Quantum AI has dragged one of quantum computing’s least glamorous chores off the whiteboard and onto real silicon. In a paper published in Science on 15 October, the company’s researchers report that a technique called magic state cultivation works on the Willow processor, cutting state-preparation errors by roughly 40-fold and lifting logical fidelity for … Read more
