Chinese scientists have made a breakthrough in the field of quantum error correction (QEC) based on superconducting quantum circuits, contributing to the development of quantum computing.

According to Xu Yuan, an assistant researcher at the Southern University of Science and Technology, although quantum information processing based on superconducting quantum circuit system has made great progress in recent years, the error rate of quantum operations is still much higher than that of a classical computer. Therefore, QEC, which protects logical qubits from noises, is extremely important.

Led by Yu Dapeng, an academician with the Chinese Academy of Sciences (CAS), the team extended the storage time of quantum information beyond the break-even point for the first time through repetitive real-time QEC. The findings were published online in the journal Nature.
