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…
Reconfigurable controlled two-qubit operation on a quantum photonic chip
H. W. Li, S. Przeslak, A. O. Niskanen +7
Integrated quantum photonics is an appealing platform for quantum information processing, quantum communication and quantum metrology. In all these applications it is necessary not…
