flag Chinese scientists used a 78-qubit quantum processor to delay quantum chaos, extending coherence time via tunable driving patterns, a step toward practical quantum computing.

flag Researchers from the Chinese Academy of Sciences and Peking University used a 78-qubit quantum processor named "Chuang-tzu 2.0" to observe and control prethermalization—a temporary stable state that delays quantum chaos. flag By applying a technique called Random Multipolar Driving, they extended the time quantum information remains coherent, slowing thermalization. flag The findings, published in Nature, show that thermalization can be tuned by adjusting driving patterns, improving control over quantum systems. flag This advance supports progress toward quantum advantage and more powerful quantum technologies.
