Demonstration of QKD Integration into 5G Campus Network

The paper deals with a proposal and implementation of the quantum key distribution in the 5G campus network. The authors share here their practical experience with the implementation of quantum cryptography in 5G which has been achieved within projects the NATO QUANTUM5 and the Czech Ministry of Interior NeSPoQ, both project contributing to the security of 5G mobile networks. Finally, the results of the experimental research demonstrate how the network performance is affected by the use of QKD.
