Abstract

Quantum communication (QC) represents a key enabler for many quantum applications. However, low information rates and short propagation distances, limit the development of this ﬁeld and its practical applications. High-dimensional (Hi-D) QC can address these challenges enhancing the information rate and the systems error tolerance. We transmit, for the ﬁrst time ever, Hi-D quantum states prepared in four orbital angular momentum (OAM) modes in a 1.2 km long OAM-carrying ﬁber. Furthermore, we successfully implement a real-time decoy-state Hi-D QKD protocol, and demonstrate the highest secret key rate and longest transmission distance of OAM-QKD presented to date
