Recently, a significant breakthrough was made by Associate Professor Deng Dongling's research group at the Institute for Interdisciplinary Information Sciences, Tsinghua University. In collaboration with the research teams of Wang Haohua and Song Chao from the School of Physics at Zhejiang University, they successfully conducted, for the very first time, an experimental demonstration of quantum error correction using high-rate bivariate bicycle codes. This feat was accomplished on a superconducting quantum processor equipped with long-range couplers.

To achieve this milestone, the research team embarked on a co-design and fabrication process, resulting in the creation of a 32-qubit superconducting quantum chip dubbed 'Kunlun.' Leveraging this advanced chip, they were able to implement two distinct types of bivariate bicycle codes and successfully carry out multiple rounds of quantum error correction.

The experimental outcomes were remarkable, revealing that the average logical error rates for the [[18,4,4]] code and the [[18,6,3]] code stood at 8.91% and 7.77%, respectively. This groundbreaking achievement has been duly recognized and published in the prestigious journal Nature Physics.
