Practical security analysis of a continuous-variable quantum random number generator with a noisy local oscillator
Weinan Huang, Yi-Chen Zhang, Ziyong Zheng +3
A quantum random-number generator (QRNG) can theoretically generate unpredictable random numbers with perfect devices and is an ideal and secure source of random numbers for crypto…
Bias-free source-independent quantum random number generator
Ziyong Zheng, Yi-Chen Zhang, Min Huang +3
A bias-free source-independent quantum random number generator scheme based on the measurement of vacuum fluctuation is proposed to realize the effective elimination of system bias…
A modified practical homodyne detector model for continuous-variable quantum key distribution: detailed security analysis and improvement by the phase-sensitive amplifier
Yundi Huang, Yi-Chen Zhang, Luyu Huang +1
The practical homodyne detector model of continuous-variable quantum key distribution models the inherent imperfections of the practical homodyne detector, namely the limited detec…
Finite-size analysis of continuous variable source-independent quantum random number generation
Junyu Zhang, Yi-Chen Zhang, Ziyong Zheng +3
We study the impact of finite-size effect on continuous variable source-independent quantum random number generation. The central-limit theorem and maximum likelihood estimation th…
