Google’s Quantum Echoes algorithm achieves verifiable quantum advantage, outperforming classical supercomputers by 13,000x

Google’s Quantum Echoes algorithm on the 105‑qubit Willow chip achieved a verified 13,000× speedup over classical supercomputers, as reported in Nature on October 21. Led by Hartmut Neven and Vadim Smelyanskiy, the system analyzes molecular structures akin to NMR data, advancing drug discovery and materials science. This marks a practical quantum leap connecting theory to real‑world applications.
