标题： Authentication of Continuous-Variable Quantum Messages

摘要： 我们引入了第一个针对连续变量状态的量子认证方案。 我们的方案基于陷阱态，并是对Broadbent等人（arXiv:1211.1080）提出的离散变量方案的改编，但在选择陷阱数量方面有更多的自由度。 我们提供了安全性证明，主要遵循Broadbent和Wainewright（arXiv:1607.03075）的方法。 作为证明的必要组成部分，我们推导出了连续变量的泡利旋转模拟。 显示英文摘要

摘要： We introduce the first quantum authentication scheme for continuous-variable states. Our scheme is based on trap states, and is an adaptation of a discrete-variable scheme by Broadbent et al. (arXiv:1211.1080), but with more freedom in choosing the number of traps. We provide a security proof, mostly following the approach of Broadbent and Wainewright (arXiv:1607.03075). As a necessary ingredient for the proof we derive the continuous-variable analogue of the Pauli Twirl.
