Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol
capable of maintaining information-theoretic security. Given the recent advances in QKD …

The dawn of softwarized networks enables Network Slicing (NS) as an important technology
towards allocating end-to-end logical networks to facilitate diverse requirements of emerging …

Quantum key distribution (QKD) has demonstrated a great potential to provide future-
proofed security, especially for 5G and beyond communications. As the critical infrastructure …

Large-scale quantum networks with thousands of nodes require scalable network protocols
and physical hardware to realize. In this paper, we introduce packet switching as a paradigm …

A quantum channel is a physical media able to carry quantum signals. Quantum key
distribution (QKD) requires direct quantum channels between every pair of prepare-and …

We demonstrate how the 5G network slicing model can be enhanced to address data
security requirements. In this work, we demonstrate two different slice configurations, with …

Featured Application The results of this paper provide a reference for the future design of a
quantum-secured 5G/B5G optical edge layer, assisted by novel integration strategies of …

We demonstrate for the first time a four-node trusted-node-free metro network configuration
with dynamic discrete-variable quantum key distribution DV-QKD networking capabilities …

The potential synergy between quantum communications and future wireless
communication systems is explored. By proposing a quantum-native or quantum-by-design …

The research leading to the published results was supported by the Ministry of the Interior of
the Czech Republic under grant ID VJ01010008 within the project Network Cybersecurity in …
