Google’s five-stage roadmap is a structured model that explains how quantum algorithms move from abstract theory to real-world applications, guiding researchers toward measurable usefulness instead of hardware-driven milestones. “Sometimes, history happens all at once. A few short years can usher in decades of progress and innovation. We’re now seeing that with quantum computing. Forty years of research, work and investment are converging, and the grand challenge of building large-scale, capable quantum computers is within humanity’s reach.” — Ryan Babbush, Director of Research, Quantum Algorithms and Applications. As real quantum computers come within humanity’s reach, Google’s Quantum AI team has proposed a five-stage framework to tighten scientists’ grasp on developing useful quantum computing applications, arguing that the next era of progress depends as much on sociology and verification as on hardware and algorithms.
