- According to Google, Quantum Echoes ran 13,000 times faster on the Willow chip than the world’s fastest supercomputers.
- Google called it the first verifiable quantum advantage, whose results other quantum systems can independently repeat and confirm.
- The algorithm sends a controlled signal, slightly disturbs the system, reverses the process, and detects the returning echo.
- Google said the achievement could support drug discovery, better batteries, materials science, cleaner energy, and quantum technologies.
This is the first time a quantum computer has successfully run a verifiable algorithm that surpasses classical supercomputers.— Google said in a blog post announcing Quantum Echoes.

- Google’s Quantum AI Lab in Goleta announced a successful run of the Quantum Echoes algorithm on the superconducting Willow processor.
- The 105-qubit chip operates near absolute zero, uses error correction, and achieves single-qubit fidelities above 99.9 percent.
- The method could analyze molecular structures, support new drugs and materials, and generate training data for scientific AI.
- Quantum computing remains experimental; independent researchers view Google’s work as meaningful progress between theoretical physics and practical technology.
