Quantum discord of ensemble of quantum states
Yao Yao, Jing-Zheng Huang, Xu-Bo Zou +4
We highlight an information-theoretic meaning of quantum discord as the gap between the ac- cessible information and the Holevo bound in the framework of ensemble of quantum states…

Quantum discord in quantum random access codes and its connection with dimension witness
Yao Yao, Hong-Wei Li, Xu-Bo Zou +6
We exploit quantum discord (and geometric discord) to detect quantum correlations present in a well-known communication model called quantum random access codes (QRACs), which has…

Effect of Intensity Modulator Extinction on Practical Quantum Key Distribution System
Jing-Zheng Huang, Zhen-Qiang Yin, Shuang Wang +3
We study how the imperfection of intensity modulator effects on the security of a practical quantum key distribution system. The extinction ratio of the realistic intensity modulat…
