论文摘要
在受信任的量子噪声方案中研究了适用于量子密钥分布的乒乓协议，其中合法各方可以在本地添加噪声。对于研究良好的攻击模型，我们展示了增加噪声的非致力量子非马克维亚性可以提高关键率。我们还指出，爱丽丝和鲍勃无法通过在其测量后数据中添加局部经典噪声来获得这种噪声引起的优势。
The ping-pong protocol adapted for quantum key distribution is studied in the trusted quantum noise scenario, wherein the legitimate parties can add noise locally. For a well-studied attack model, we show how non-unital quantum non-Markovianity of the added noise can improve the key rate. We also point out that this noise-induced advantage cannot be obtained by Alice and Bob by adding local classical noise to their post-measurement data.
