Google Willow Chip Slashes Quantum Resource Costs 40x

Google's Willow quantum chip produces magic states with 99.99% fidelity while reducing their production costs by roughly 40x, according to company data. The efficiency gain clears a key resource bottleneck that previously hindered the reliability of quantum systems. By optimising the production of these states, Google can improve stability without simply adding more hardware, potentially bringing practical quantum computers closer to deployment.
