Google unveiled Quantum Echoes, an algorithm that achieved a ~13,000× speed-up over leading classical methods on its Willow chip, with a focus on producing verifiable results applicable to AI, molecular structure analysis, and materials science. This marks a shift from “toy problems” toward utility-grade quantum workloads.
