Abstract

In this paper, we continue the study of the quantum cryptographic GG02 protocol, performed using the approach based on the subcarrier waves. We modify the scheme via heterodyne detection and perform security analysis for the full trusted hardware noise model in the presence of collective attacks with finite-key effects. It is shown that the system can potentially distribute the key even if the level of losses in the channel is above 9 dB. This result is consistent with the general technical level and comply with modern standards of practical CV-QKD systems. Finally, the system under consideration fully meets the criterion of composability.

高斯调制的子载波连续变量量子密钥分发:可组合安全性分析

在本文中，我们继续研究使用基于子载波的方法实现的量子密码GG02协议。我们通过外差检测修改了该方案，并对存在有限密钥效应的集体攻击的完全可信硬件噪声模型进行了安全性分析。结果表明，在信道损耗大于9db的情况下，该系统仍能实现密钥的潜在分配。该结果与一般技术水平一致，符合实用CV-QKD系统的现代标准。最后，所考虑的系统完全满足可组合性标准。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
