基于Qutri的半量子密钥分发协议

Qutrit-based semi-quantum key distribution protocol

Hasnaa Hajji, Morad El Baz

摘要:

提出了一种基于三维量子态的半量子密钥分发(SQKD)协议。通过推导出一个下界的密钥速率,在渐近的情况下,作为量子信道的噪声的函数,我们发现,该协议有更大的容忍噪声相比,以前的2维SQKD协议,提高了密钥速率。我们的研究结果表明,类似于全量子密钥分发协议,增加系统的维数可以增加半量子密钥分发的噪声容忍度,以及。

英文摘要:

This article provides the unconditional security of a semi quantum key distribution (SQKD) protocol based on 3-dimensional quantum states. By deriving a lower bound for the key rate, in the asymptotic scenario, as a function of the quantum channel's noise, we find that this protocol has improved secret key rate with much more tolerance for noise compared to the previous 2-dimensional SQKD protocol. Our results highlight that, similar to the fully quantum key distribution protocol, increasing the dimension of the system can increase the noise tolerance in the semi-quantum key distribution, as well.
