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…
Improving the lower bound to the secret-key capacity of the thermal amplifier channel
Gan Wang, Carlo Ottaviani, Hong Guo +1
We consider the noisy thermal amplifier channel, where signal modes are amplified together with environmental thermal modes. We focus on the secret-key capacity of this channel, wh…

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…
User-defined quantum key distribution
Zhengyu Li, Yi-Chen Zhang, Hong Guo
Quantum key distribution (QKD) provides secure keys resistant to code-breaking quantum computers. As headed towards commercial application, it is crucial to guarantee the practical…
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…
Composable security analysis of continuous-variable measurement-device-independent quantum key distribution with squeezed states for coherent attacks
Ziyang Chen, Yi-Chen Zhang, Gan Wang +2
Measurement-device-independent quantum key distribution protocol, whose security analysis does not rely on any assumption on the detection system, can immune the attacking against…
