Abstract

Recently photon-added quantum light states have been studied, mainly for discussions of the classical-quantum frontier. In this work we discuss the use of photon-added coherent states (PACS) in quantum communication. Firstly, we present the PACS-based qubit and the quantum circuit for its teleportation. Following, we show a quantum key distribution scheme emplying photon-added coherent and thermal states.
