QNUS: Reducing Terminal Resources in Quantum Secure Direct Communication Network Using Switches
Peng-Hao Niu, Feihao Zhang, Xiu-Wei Chen, Min Wang, Gui‐Lu Long · Quantum Engineering · 2022
The quantum network is an indispensable step toward multiuser and wide-area information interchange in the course of the development of quantum technology. When designing and deploying a quantum network, availability, robustness, flexibility, and expenditure need to be considered in a balanced way. In this article, we propose a network connected through optical switches, QNUS, that requires only terminals in the number of nodes in a quantum network, which is a great saving of resources.
