Google’s quantum team says its Willow processor ran a new algorithm called Quantum Echoes that solved a molecular-simulation task roughly 13,000× faster than the best classical methods on top supercomputers. Based on reports, the run is being presented as a verifiable quantum advantage and was published alongside technical notes from Google.

Google Quantum Chip Beats Supercomputers

The experiment used Willow hardware and an algorithm tailored to a specific scientific problem, not a general-purpose attack on everyday encryption. According to Google’s post, the work produces verifiable outputs that are useful for chemistry and materials research.

That distinction matters because a speed win on one problem does not automatically mean the same device can run all quantum algorithms at the
