We give the first information-theoretic security proof of the `Round Robin Differential Phase Shift' Quantum Key Distribution scheme. Our proof consists of the following steps. We construct an EPR var...
Round-Robin Differential Phase-Shift (RRDPS) is a Quantum Key Distribution (QKD) scheme proposed by Sasaki, Yamamoto and Koashi in 2014. It works with high-dimensional quantum digits (qudits). Its mai...
