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…
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…
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…
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…
Security of "Counterfactual Quantum Cryptography"
Zhen-Qiang Yin, Hong-Wei Li, Zheng-Fu Han +1
Recently, a "counterfactual" quantum key distribution scheme was proposed by Tae-Gon Noh [1]. In this scheme, two legitimate distant peers may share secret keys even when the infor…
