# Key-Rate Bound of a Semi-Quantum Protocol Using an Entropic Uncertainty Relation

@article{Krawec2018KeyRateBO, title={Key-Rate Bound of a Semi-Quantum Protocol Using an Entropic Uncertainty Relation}, author={Walter O. Krawec}, journal={2018 IEEE International Symposium on Information Theory (ISIT)}, year={2018}, pages={2669-2673} }

In this paper we present a new proof technique for semi-quantum key distribution (SQKD) protocols which makes use of a quantum entropic uncertainty relation to bound an adversary's information. We develop several new techniques for analyzing SQKD protocols; furthermore, our new proof may hold application in the security analysis of other semi-quantum protocols or protocols relying on two-way quantum communication.
