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…
Supersensitivity of Kerr phase estimation with two-mode squeezed vacuum states
Yun-Feng Guo, Wei Zhong, Lan Zhou +1
We analytically investigate the sensitivity of Kerr nonlinear phase estimation in a Mach-Zehnder interferometer with two-mode squeezed vacuum states. We find that such a metrologic…
Experimental one-step deterministic entanglement purification
Cen-Xiao Huang, Xiao-Min Hu1, Bi-Heng Liu +4
Entanglement purification is to distill high-quality entangled states from low-quality entangled states. It is a key step in quantum repeaters, determines the efficiency and commun…
