Foreign media: Chinese scientists have made a major breakthrough in the field of quantum chaos control, for the first time directly observing and manipulating the "prethermalisation" transition state in a quantum system. The research team used the 78-qubit superconducting processor "Zhuangzi 2.0" developed by the Institute of Physics, Chinese Academy of Sciences, successfully slowing down the quantum decoherence process, providing a key tool for managing complex quantum environments.
After being disturbed, a quantum system naturally returns to a balanced state, with energy and information gradually diffusing until evenly distributed. This process is similar to pushing a pendulum, which eventually stops. This poses a significant challenge for quantum computing, as quantum computing relies on preserving information intact. If the system changes too quickly, the computational results become difficult to store and extract. Currently, classical computers cannot predict how long this process will take or what factors influence it.
This study was published in the journal Nature on January 28, 2026, marking an important advancement in the field of quantum information protection.
