摘要

本文在光背对背160km标准单模光纤中进行了基于3通道qam映射和DFTs-OFDM的量子噪声流密码方案实验。在双极化I/Q调制器系统中，三维映射与dft - ofdm的融合为QAM/QNSC提供了足够的安全性。值得注意的是，与传统的2D映射相比，所提出的3d映射方法具有改进的最小欧几里德距离和误码率性能。实验结果表明，与传统QAM/QNSC相比，我们设计的三通道QAM/QNSC系统在相同基长下具有更好的传输性能和更高的安全性能。

Quantum Noise Stream Cipher Scheme Based on 3-Channel-QAM With 3D Mapping and DFTs-OFDM

In this letter, we conduct an experiment of quantum noise stream cipher scheme based on 3-channel-QAM mapping and DFTs-OFDM in optical back-to-back and 160km standard single mode fiber. The fusion of 3D mapping and DFTs-OFDM offers sufficient security for QAM/QNSC within the dual polarization I/Q modulator system. Notably, the proposed 3D-mapping approach demonstrates improved minimum Euclidean distance and bit error rate performance compared to conventional 2D mapping. Experimental results confirm that our 3-channel-QAM/QNSC system achieves better transmission and higher security performance at the same base length than conventional QAM/QNSC.
