Prof. Li Chuanfeng, Prof. Huang Yunfeng, Prof. Chen Geng, and their colleagues from Prof. Guo Guangcan's group at the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with Swiss academicians, have certified device-independent genuine multipartite entanglement for the first time and invented a new method to certify genuine multipartite entanglement without making any assumptions on the internal functioning of the measurement device. Their work was published in Physical Review Letters.
