A short note on the security of Round-Robin Differential Phase-Shift QKD
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 main advantage is that it tolerates more noise than qubit-based schemes while being easy to implement.
