Quantum key distribution (QKD) guarantees the secure communication betweenlegitimate parties with quantum mechanics. High-dimensional QKD (HDQKD) notonly increases the secret key rate but also tolerates higher quantum bit errorrate (QBER). Many HDQKD experiments have been realized by utilizingorbital-angular-momentum (OAM) photons as the degree of freedom (DOF) of OAM ofthe photon is a prospective resource for HD quantum information. In this workwe proposed and characterized that a high-quality HDQKD based onpolarization-OAM hybrid states can be realized by utilizing state mappingbetween different DOFs. Both the preparation and measurement procedures of theproof-of-principle verification experiment are simple and stable. Ourexperiment verified that $(0.60\pm 0.06)\%$ QBER and $1.849\pm 0.008$ bitssecret key rate per sifted signal can be achieved for a four-dimensional QKDwith the weak coherent light source and decoy state method.
