基于Qudit系统的量子密钥分发安全性证明

Security Proof for Quantum Key Distribution Using Qudit Systems

Lana Sheridan, Valerio Scarani

摘要:

我们提供了两个家庭的量子密钥分发协议,使用$d$-维量子系统的安全界限,防止相干攻击。在渐近状态下,固定噪声的密钥速率和对噪声的鲁棒性都随着$d$的增加而增加。发现有限密钥校正对$d\lesssim 20$几乎不敏感。

英文摘要:

We provide security bounds against coherent attacks for two families of quantum key distribution protocols that use $d$-dimensional quantum systems. In the asymptotic regime, both the secret key rate for fixed noise and the robustness to noise increase with $d$. The finite-key corrections are found to be almost insensitive to $d\lesssim 20$.
