Efficient multipartite entanglement purification with non-identical states
Hao Qin, Ming-Ming Du, Xi-Yun Li +3
We present an efficient and general multipartite entanglement purification protocol (MEPP) for N-photon systems in Greenberger-Horne-Zeilinger (GHZ) states with non-identical input…
Relation between quantum illumination and quantum parameter estimation
Wei Zhong, Dong-Qing Wang, Wen-Yi Zhu +3
Quantum illumination leverages entangled lights to detect the presence of low-reflectivity objects within a thermal environment. In a related vein, quantum parameter estimation uti…
Advances in quantum entanglement purification
Peishun Yan, Lan Zhou, Wei Zhong +1
Since its discovery, the quantum entanglement becomes a promising resource in quantum communication and computation. However, the entanglement is fragile due to the presence of noi…
Device-independent quantum secure direct communication with single photon sources
Lan Zhou, Bao-Wen Xu, Wei Zhong +1
Quantum secure direct communication (QSDC) can directly transmit secrete messages through quantum channel. Device-independent (DI) QSDC can guarantee the communication security rel…
Even- and odd-orthogonality properties of the Wigner D-matrix and their metrological applications
Wei Zhong, Lan Zhou, Cui-Fang Zhang +1
The Wigner D-matrix is essential in the course of angular momentum techniques. We here derive the new even- and odd-orthogonality properties of the Wigner D-matrix which was yet to…
