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 ...

Quantum key distribution promises ultra-secure communication by using the strange rules of quantum physics to detect eavesdroppers instantly. But even the most secure quantum link can falter if the ...

Quantum secure communication uses quantum mechanisms to secure classical (non-quantum) communication and is fundamental to national information security and socioeconomic development. One of the ...

IonQ deployed what it claims to be the largest and most complex quantum key distribution (QKD) network in Europe. The initiative came out of a project with Romanian institutions, including the ...

Quantum communication could enable uncrackable transfer of information, but most approaches rely on trusted devices. Researchers have now demonstrated that a new method that does away with this ...

Quantum entanglement occurs when two subatomic particles become linked in such a way that their properties remain connected, no matter how far apart they are. A change to one particle seems to ...
