On the 23rd, it was learned from the University of Science and Technology of China that professors Pan Jianwei, Zhu Xiaobo, Peng Chengzhi, and associate professor Chen Fusheng have achieved quantum error correction below the error correction threshold on a surface code with a code distance of 7 based on the superconducting quantum processor "Zuchongzhi 3.2", demonstrating a significant decrease in logic error rate with increasing code distance. This achievement marks a key milestone in China's achievement of "below the threshold, the more accurate the correction", and opens up a new path of "full microwave control" that is more efficient than Google in the United States, laying a key technological foundation for future large-scale fault-tolerant quantum computing. On December 22nd, the achievement was published as a cover paper and "editor's recommendation" in the international academic journal "Physical Review Letters", with a special report in the "Physics" column of the American Physical Society. The necessary condition for achieving fault-tolerant universal quantum computers is to suppress the error rate of quantum bits through quantum error correction to meet the requirements of large-scale integration. Surface code is currently one of the most mature quantum error correction schemes. However, quantum error correction requires the introduction of a large number of additional quantum bits and quantum gate operations, resulting in more noise sources and error channels. If the original error rate of physical qubits is too high, the additional errors caused by increasing the error correction code spacing will actually drown out the benefits of error correction, leading to 'more errors are corrected'. Among them, "leakage errors" are particularly deadly - as the system scale expands, the cumulative effect of leakage errors will become the main bottleneck hindering the improvement of error correction performance. Therefore, how to break through a strict "error correction threshold" for the overall control accuracy of the system, and achieve "more correct and more accurate" quantum error correction, is the key watershed to measure whether quantum computing systems can move from laboratory prototypes to practical applications. On the basis of previous research, a team from the University of Science and Technology of China proposed and successfully implemented a new "all microwave quantum state leakage suppression architecture" based on the 107 bit "Zuchongzhi 3.2" quantum processor. The research team combined a fully microwave quantum state leakage suppression architecture to achieve surface code logic bits with a code distance of 7. The experimental results show that the logic error rate significantly decreases with the increase of code distance, and the error suppression factor reaches 1.4, proving that the system has been working below the error correction threshold and successfully achieved the goal of "more correct, more accurate".
