混合编码的高效高维量子密钥分发

Efficient High-dimensional Quantum Key Distribution with Hybrid Encoding

Yonggi Jo, Hee Su Park, Seung-Woo Lee, Wonmin Son

摘要:

提出了一种基于高维量子态提高密钥速率的量子密钥分发方案。单个光子的两个自由度、轨道角动量模式和多路径模式用于对密钥信息进行编码。它的实际实现包括在当前技术范围内的光学元件,例如多端口干涉仪。我们表明,所提出的可行的协议已经提高了密钥速率与复杂度相比,以前的2维协议称为检测器设备无关的量子密钥分配。

英文摘要:

We propose a schematic setup of quantum key distribution (QKD) with an improved secret key rate based on high-dimensional quantum states. Two degrees-of-freedom of a single photon, orbital angular momentum modes, and multi-path modes, are used to encode secret key information. Its practical implementation consists of optical elements that are within the reach of current technologies such as a multiport interferometer. We show that the proposed feasible protocol has improved the secret key rate with much sophistication compared to the previous 2-dimensional protocol known as the detector-device-independent QKD.
