Google Quantum Chip Achieves Fault-Tolerant Milestone

Google DeepMind unveiled the Willow quantum computing chip in late 2024, and in 2025 published peer-reviewed results confirming it had achieved key fault-tolerance milestones, solving in minutes computations that would take classical supercomputers septillions of years. The development marked a critical step toward practical quantum advantage in drug discovery, materials design, and cryptography. The research was published in Nature and widely hailed as a generational breakthrough.
