Long-Distance Continuous-Variable Quantum Key Distribution over 202.81 km of Fiber
Yi-Chen Zhang, Ziyang Chen, Stefano Pirandola +7
Quantum key distribution provides secure keys resistant to code-breaking quantum computers. The continuous-variable version of quantum key distribution offers the advantages of hig…
Polarization attack on continuous-variable quantum key distribution
Yijia Zhao, Yi-Chen Zhang, Yundi Huang +3
The shot-noise unit (SNU) is a crucial factor for the practical security of a continuous-variable quantum key distribution system. In the most widely used experimental scheme, the…
Improvement of two-way continuous-variable quantum key distribution with virtual photon subtraction
Yijia Zhao, Yi-Chen Zhang, Zhengyu Li +2
We propose a method to improve the performance of two-way continuous-variable quantum key distribution protocol by virtual photon subtraction. The Virtual photon subtraction implem…
Finite-size analysis of continuous-variable measurement-device-independent quantum key distribution
Xueying Zhang, Yi-Chen Zhang, Yijia Zhao +3
We study the impact of the finite-size effect on the continuous-variable measurement-device-independent quantum key distribution (CV-MDI QKD) protocol, mainly considering the finit…
Numerical simulation of the optimal two-mode attacks for two-way continuous-variable quantum cryptography in reverse reconciliation
Yi-Chen Zhang, Zhengyu Li, Yijia Zhao +2
We analyze the security of the two-way continuous-variable quantum key distribution protocol in reverse reconciliation against general two-mode attacks, which represent all accessi…
