Security proof of a semi-quantum key distribution protocol

2015

Semi-quantum key distribution protocols are designed to allow two users to establish a secure secret key when one of the two users is limited to performing certain “classical” operations. There have been several such protocols …

Experimental Quantum Cryptography With Classical Users

2019 · arXiv (Cornell University)

The exploit of quantum systems allows for insights that promise to revolutionise information processing, although a main challenge for practical implementations is technological complexity. Due to its feasibility, quantum cryptography, which allows for perfectly secure …

Dynamic Routing and Post-Processing Strategies for Hybrid Quantum Key Distribution Networks

2024

In this paper, we consider hybrid quantum key distribution (QKD) networks with primarily quantum repeaters and a small number of trusted nodes. While the trusted nodes need to be trusted, the use of such nodes, …
