✅ La puce quantique de Google est 13 000 fois plus rapide que les meilleurs super PCs

✅ It’s true but we are not at a fully general quantum advantage yet. In October 2025, H Neven; VP at Google Quantum AI announced a major speed breakthrough. His team calculated that : • A 65-qubit problem took about 2 hours on their “Willow” Google’s quantum chip. • A similar 40-qubit version takes days on high-end GPUs. • Running the full 65-qubit version on the Frontier supercomputer would take an estimated 3.2 years. https://cvc.li/nIrko The experiment looked at how quantum information spreads in complex, chaotic systems using a kind of “echo” technique called the 2nd-order out-of-time-order correlator, or OTOC(2). Google Quantum AI argues that their quantum processor could help “learn” the hidden physics of a system and improve how scientists analyse magnetic materials, molecules, and chemical reactions. For example, extending the range of nuclear magnetic resonance (NMR) spectroscopy. But there are important limitations. The speedup only applies to a specific class of measurements, not to all problems. Classical simulation and the Frontier Computer are still improving. Current quantum hardware still has relatively high error rates (not fault-tolerant). The full peer-reviewed paper is here : https://cvc.li/DPLzW
