Continuous-variable quantum key distribution with Gaussian source noise
Yujie Shen, Xiang Peng, Jian Yang +1
Source noise affects the security of continuous-variable quantum key distribution (CV QKD), and is diffcult to analyze. We propose a model to characterize Gaussian source noise thr…

Experimental quantum key distribution with an untrusted source
Xiang Peng, Hao Jiang, Bingjie Xu +2
The photon statistics of a quantum key distribution (QKD) source is crucial for security analysis. In this paper, we propose a practical method, with only a beam splitter and photo…

On the Poisson Approximation to Photon Distribution for Faint Lasers
Yucheng Hu, Xiang Peng, Tiejun Li +1
It is proved, that for a certain kind of input distribution, the strongly binomially attenuated photon number distribution can well be approximated by a Poisson distribution. This…
