Continuous-variable quantum key distribution network based on entangled states of optical frequency combs
Hai Zhong, Qianqian Hu, Zhiyue Zuo +3
Continuous-variable quantum key distribution (CVQKD) features a high key rate and compatibility with classical optical communication. Developing expandable and efficient CVQKD netw…
Long-distance continuous-variable quantum key distribution using separable Gaussian states
Jian Zhou, Duan Huang, Ying Guo
Continuous-variable quantum key distribution (CVQKD) is considered to be an alternative to classical cryptography for secure communication. However, its transmission distance is re…
Dual-phase-modulated plug-and-play measurement-device-independent continuous-variable quantum key distribution
Qin Liao, Ying Guo, Yijun Wang +1
We suggest an improved plug-and-play measurement-device-independent (MDI) continuous-variable quantum key distribution (CVQKD) via the dual-phase modulation (DPM), aiming to solve…
Security of Continuous-Variable Quantum Key Distribution with Discrete Modulation against General Attacks
Jian Zhou, Ying Guo, Duan Huang +1
We provide a security analysis of continuous-variable quantum key distribution (CVQKD) with discrete modulation against general attacks in a realistic finite-size regime. To realiz…
Composable security of unidimensional continuous-variable quantum key distribution
Qin Liao, Ying Guo, Cailang Xie +3
We investigate the composable security of unidimensional contin- uous variable quantum key distribution (UCVQKD), which is based on the Gaussian modulation of a single quadrature o…
