Improved Four-state Continuous-variable Quantum Key Distribution with Long Secure Distance
Jian Yang, Bingjie Xu, Xiang Peng +1
The four-state continuous-variable quantum key distribution (CVQKD) protocol has a long practical secure distance \cite{Leverrier_PRL_2009}, while it has the difficulty of paramete…
Source monitoring for continuous-variable quantum key distribution
Jian Yang, Xiang Peng, Hong Guo
The noise in optical source needs to be characterized for the security of continuous-variable quantum key distribution (CVQKD). Two feasible schemes, based on either active optical…
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…
Security bound of continuous-variable quantum key distribution with noisy coherent states and channel
Yong Shen, Jian Yang, Hong Guo
Security of a continuous-variable quantum key distribution protocol based on noisy coherent states and channel is analyzed. Assuming the noise of coherent states is induced by Fred…
