Researchers at the University of Science and Technology of China have achieved a breakthrough in quantum error correction using their 107-qubit Zuchongzhi 3.2 superconducting quantum processor, demonstrating fault-tolerant behavior for the first time outside the U.S. This advancement, detailed in Physical Review Letters, involves an all-microwave method that effectively suppresses leakage errors, achieving an error-suppression factor of 1.4, though practical applications still require significantly larger qubit scales.
