我国在量子纠错领域达到关键里程碑

Core Viewpoint - The research team from the University of Science and Technology of China has achieved a significant milestone in quantum error correction using the "Zu Chongzhi 3.2" superconducting quantum processor, demonstrating a logical error rate below the error correction threshold, paving the way for large-scale fault-tolerant quantum computing [1][2]. Group 1 - The achievement involves implementing quantum error correction with a code distance of 7, resulting in a significant decrease in logical error rates as the code distance increases [1][2]. - The research introduces a novel "full microwave quantum state leakage suppression architecture," which has shown to work below the error correction threshold, achieving the goal of "correcting more leads to more accuracy" [2]. - The error suppression factor reached 1.4, indicating that the system operates effectively within the desired parameters for quantum error correction [2]. Group 2 - The full microwave quantum state leakage suppression architecture offers inherent frequency division multiplexing characteristics, providing significant advantages in hardware efficiency and scalability compared to Google's technology [3]. - This advancement presents a more favorable solution for constructing million-qubit level quantum computers in the future [3].
