Measurement-device-independent quantum key distribution with uncharacterized qubit sources
Zhen-Qiang Yin, Chi-Hang Fred Fung, Xiongfeng Ma +6
Measurement-device-independent quantum key distribution (MDIQKD) is proposed to be secure against any possible detection attacks. The security of the original proposal relies on th…
Phase-encoded measurement device independent quantum key distribution with practical spontaneous parametric-down-conversion sources
Chun Zhou, Wan-Su Bao, Wei Chen +4
Measurement-device-independent quantum key distribution (MDI-QKD) with weak coherent sources has been widely and meticulously analyzed. However, the analysis for MDI-QKD with spont…
The effect of channel decoherence on entangled coherent states: A theoretical analysis
Yao Yao, Hong-Wei Li, Zhen-Qiang Yin +2
We analyse decoherence properties of entangled coherent states (ECSs) due to channel losses, and compare to the performance of bi-photon Bell states. By employing the concept of "e…
Bell violation versus geometric measure of quantum discord and their dynamical behavior
Y. Yao, H. W. Li, M. Li +3
Motivated by recent numerous works on the interplay among various measures of quantum correlations, we aim to investigate the relationship between the violation of Clauser-Horne-Sh…
Geometric interpretation of the geometric discord
Yao Yao, Hong-Wei Li, Zhen-Qiang Yin +1
We investigate the level surfaces of geometric measure of quantum discord, and provide a pictorial interpretation of geometric discord for Bell-diagonal states. We have observed it…
Quantum Hacking on Continuous-Variable Quantum Key Distribution System using a Wavelength Attack
Jing-Zheng Huang, Christian Weedbrook, Zhen-Qiang Yin +5
The security proofs of continuous-variable quantum key distribution are based on the assumptions that the eavesdropper can neither act on the local oscillator nor control Bob's bea…
