In this work, we introduce a high-dimensional polarization-phase (PoP)-based quantum key distribution protocol, briefly named PoP[Formula: see text], where [Formula: see text] is the dimension of a hybrid quantum state including polarization and phase degrees of freedom of the same photon, and [Formula: see text] is the number of mutually unbiased bases. We present a detailed description of the PoP[Formula: see text] protocol as a special case, and evaluate its security against various individual and coherent eavesdropping strategies, and in each case, we compare it with the BB84 and the two-dimensional (TD)-PoP protocols. In all the strategies, the error threshold and the effective transmission rate of the PoP[Formula: see text] protocol are far greater than the other two protocols. Unlike most high-dimensional protocols, the simplicity of producing and detecting the qudits and the use of conventional components (such as traditional single-photon sources and quantum channels) are among the features of the PoP[Formula: see text] protocol.

使用极化相位编码的高维量子密钥分配：安全分析

在这项工作中，我们介绍了一种基于高维极化相位（PoP）的量子密钥分发协议，简称 PoP[公式：见正文]，其中 [公式：见正文] 是包括极化在内的混合量子态的维数和相同光子的相位自由度，[公式：见正文]是相互无偏的碱基数。我们将 PoP[Formula: see text] 协议作为一个特例进行详细描述，并评估其针对各种单独和连贯窃听策略的安全性，并且在每种情况下，我们将其与 BB84 和二维（TD )-PoP 协议。在所有策略中，PoP[公式：见正文]协议的误码阈值和有效传输速率都远大于其他两种协议。与大多数高维协议不同，
