论文摘要
量子安全的直接通信提供了一种直接的手段，可以通过合法用户中的量子状态传达秘密信息。在过去的二十年中，在理论上和实验上都取得了长足的进步。但是，对其的安全分析仍然留在婴儿中。该领域中的一些实际问题要紧急解决，例如探测器效率不匹配，侧道效果和源缺陷，正在推动更加无可挑剔的解决方案的诞生。在本文中，我们建立了一个由数字驱动的安全分析的新框架，其中所有实际问题都可以自然考虑。考虑到现实世界实验条件，我们将此框架应用于DL04协议的几种变体。此外，我们提出了两种优化方法来处理框架的数值部分，以便在实践中满足不同的要求。考虑到这些属性，我们预计强大的框架将为该领域开发的广泛途径开放。
Quantum secure direct communication provides a direct means of conveying secret information via quantum states among legitimate users. The past two decades have witnessed its great strides both theoretically and experimentally. However, the security analysis of it still stays in its infant. Some practical problems in this field to be solved urgently, such as detector efficiency mismatch, side-channel effect and source imperfection, are propelling the birth of a more impeccable solution. In this paper, we establish a new framework of the security analysis driven by numerics where all the practical problems may be taken into account naturally. We apply this framework to several variations of the DL04 protocol considering real-world experimental conditions. Also, we propose two optimizing methods to process the numerical part of the framework so as to meet different requirements in practice. With these properties considered, we predict the robust framework would open up a broad avenue of the development in the field.
