A collaborative team of Chinese scientists, among whom are Pan Jianwei, Zhu Xiaobo, and Mei Feng, harnessed the capabilities of the programmable superconducting quantum processor known as 'Zuchongzhi 2' to achieve and identify, for the very first time, higher-order non-equilibrium topological phases within quantum systems. This remarkable accomplishment stands as a pivotal milestone in the realm of quantum simulation, facilitating the exploration of intricate topological states of matter. Moreover, it paves the way for the realization of quantum supremacy through the utilization of superconducting quantum processors. The pertinent research findings have been duly published in the esteemed international academic journal, Science.
