To push beyond this boundary, the team developed a quantum repeater system capable of creating memory–memory entanglement between two separate nodes. By linking these nodes through entanglement ...

Quantum key distribution (QKD) exploits the intrinsic properties of quantum mechanics to enable the secure exchange of cryptographic keys between distant parties. By utilising quantum states of light, ...

A team of researchers led by PAN Jianwei, ZHANG Qiang, and BAO Xiaohui from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), along with other ...
