Relation between semi- and fully-device-independent protocols
Hong-Wei Li, Piotr Mironowicz, Marcin Pawlowski +7
We study the relation between semi and fully device independent protocols. As a tool, we use the correspondence between Bell inequalities and dimension witnesses. We present a meth…
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…
Wavelength attack scheme on continuous-variable quantum key distribution system using heterodyne detection protocol
Jing-Zheng Huang, Zhen-Qiang Yin, Shuang Wang +4
The security proof of continuous variable quantum key distribution(CV QKD) based on two assumptions that the eavesdropper can neither act on the local oscillator nor control Bob's…
Performance of various correlation measures in quantum renormalization-group method: A case study of quantum phase transition
Yao Yao, Hong-Wei Li, Chun-Mei Zhang +3
We have investigated quantum phase transition employing the quantum renormalization group (QRG) method while in most previous literature barely entanglement (concurrence) has been…
2-GHz clock quantum key distribution over 260 km of standard telecom fiber
Shuang Wang, Wei Chen, Jun-Fu Guo +5
We report a demonstration of quantum key distribution (QKD) over a standard telecom fiber exceeding 50 dB in loss and 250 km in length. The differential phase shift QKD protocol wa…
Field test of the wavelength-saving quantum key distribution network
Shuang Wang, Wei Chen, Zhen-Qiang Yin +13
We propose a wavelength-saving topology of quantum key distribution(QKD) network based on passive optical elements, and report the field test of this network on the commercial tele…
