Abstract

Six-state Quantum Key Distribution (QKD) achieves the highest key rate in the class of qubit-based QKD schemes. The standard security proof, which has been developed since 2005, invokes complicated theorems involving smooth R\'{e}nyi entropies. In this paper we present a simpler security proof for 6-state QKD that entirely avoids R\'{e}nyi entropies. This is achieved by applying state smoothing directly in the Bell basis. We obtain the well known asymptotic rate, but with slightly more favorable finite-size terms. We furthermore show that the same proof technique can be used for 6-state quantum key recycling.

一个更简单的六态量子密钥分发安全性证明
在基于量子比特的量子密钥分发方案中,六态量子密钥分发(QKD)实现了最高的密钥速率。自2005年以来开发的标准安全性证明调用了涉及光滑R\ {e}nyi熵的复杂定理。在本文中,我们提出了一个更简单的六态QKD安全性证明,它完全避免了R\ {e}nyi熵。这是通过在贝尔基中直接应用状态平滑来实现的。我们得到了众所周知的渐近速率,但有稍微有利的有限大小项。我们进一步证明了同样的证明技术可以用于六态量子密钥的回收。
