Continuous-variable source-device-independent quantum key distribution against general attacks
Yi-Chen Zhang, Ziyang Chen, Christian Weedbrook +2
The continuous-variable quantum key distribution with entanglement in the middle, a semi-device-independent protocol, places the source at the untrusted third party between Alice a…
1.2 GHz Balanced Homodyne Detector for Continuous-Variable Quantum Information Technology
Xiaoxiong Zhang, Yi-Chen Zhang, Zhengyu Li +2
Balanced homodyne detector (BHD) that can measure the field quadratures of coherent states has been widely used in a range of quantum information technologies. Generally, the BHD t…
High Efficiency Postprocessing for Continuous-variable Quantum Key Distribution: Using All Raw Keys for Parameter Estimation and Key Extraction
Xiangyu Wang, Yi-Chen Zhang, Song Yu +1
High efficiency postprocessing of continuous-variable quantum key distribution system has a significant impact on the secret key rate and transmission distance of the system. Curre…
High-speed Implementation of Length-compatible Privacy Amplification in Continuous-variable Quantum Key Distribution
Xiangyu Wang, Yi-Chen Zhang, Song Yu +1
Privacy amplification is an indispensable step in postprocessing of continuous-variable quantum key distribution (CV-QKD), which is used to distill unconditional secure keys from i…
6 Gbps real-time optical quantum random number generator based on vacuum fluctuation
Ziyong Zheng, Yi-Chen Zhang, Weinan Huang +2
We demonstrate a 6 Gbps real-time optical quantum random number generator by measuring vacuum fluctuation. To address the common problem that speed gap exists between fast randomne…
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…
