The High-tech Research and Development Center under the Ministry of Science and Technology released China’s top ten scientific advances of 2021 on Monday, including ‘quantum walks on a programmable two-dimensional 62-qubit superconducting processor” achieved by the University of Science and Technology of China (USTC). A USTC research team led by quantum physicist Pan Jianwei developed ‘Zuchongzhi’ - a 62-qubit programmable superconducting quantum computing prototype, and used the device to demonstrate programmable two-dimensional quantum walks. The study was published in the international academic journal Science on May 7, 2021. This achievement lays a technical foundation for the demonstration of quantum superiority in superconducting quantum systems and highlights potential applications in areas like quantum search algorithm and general quantum computing. The top ten scientific advances were selected from 30 ones based on an online voting by over 3,500 scientists and experts including academicians of Chinese Academy of Sciences and Chinese Academy of Engineering.
