Chinese researchers have made a crucial breakthrough in quantum communication, boosting the future development of secure satellite-based long-distance and global quantum communication networks. 

The research team comprising Chen Xianfeng from Shanghai Jiaotong University and Li Yuanhua from Jiangxi Normal University constructed a 15-user quantum secure direct communication (QSDC) network. The network enabled the direct transmission of confidential information among the users connected by the network for the first time.

Their study titled "A 15-user quantum secure direct communication network" was published in the scientific journal Light: Science and Application.

Quantum communication is a cutting-edge information technology that promises ultra-secure transmission of data. Scientists have developed many models for such transmission, including quantum key distribution (QKD), quantum teleportation, and QSDC.
