Entanglement Structure Detection via Machine Learning
Changbo Chen, Changliang Ren, Hongqing Lin +1
Detecting the entanglement structure, such as intactness and depth, of an n-qubit state is important for understanding the imperfectness of the state preparation in experiments. Ho…
Observation of nonlocality sharing via not-so-weak measurements
Tianfeng Feng, Changliang Ren, Yuling Tian +4
Nonlocality plays a fundamental role in quantum information science. Recently, it has been theoretically predicted and experimentally demonstrated that the nonlocality of an entang…
Quantum radar
Lorenzo Maccone, Changliang Ren
We propose a quantum metrology protocol for the localization of a non-cooperative point-like target in three-dimensional space, by illuminating it with electromagnetic waves. It em…
Steerability detection of arbitrary 2-qubit state via machine learning
Changliang Ren, Changbo Chen
Quantum steering is an important nonclassical resource for quantum information processing. However, even lots of steering criteria exist, it is still very difficult to efficiently…
Experimental Simultaneous Learning of Multiple Non-Classical Correlations
Mu Yang, Chang-liang Ren, Yue-chi Ma +7
Non-classical correlations can be regarded as resources for quantum information processing. However, the classification problem of non-classical correlations for quantum states rem…
Mapping Criteria of Nonlocality-Steerability in Qudit-Qubit Systems and Steerability-Entanglement in Qubit-Qudit Systems
Changbo Chen, Changliang Ren, Xiang-Jun Ye +1
Entanglement, quantum steering and nonlocality are distinct quantum correlations which are the resources behind various of quantum information and quantum computation applications.…
Deriving Einstein-Podolsky-Rosen steering inequalities from the few-body Abner Shimony inequalities
Jie Zhou, Hui-Xian Meng, Shu-Han Jiang +4
For the Abner Shimony (AS) inequalities, the simplest unified forms of directions attaining the maximum quantum violation are investigated. Based on these directions, a family of E…
Chained Einstein-Podolsky-Rosen steering inequalities with improved visibility
Hui-Xian Meng, Jie Zhou, Changliang Ren +2
It is known that the linear n-setting steering inequalities introduced in Ref. [Nature Phys. 6, 845 (2010)] are very efficient inequalities in detecting steerability of the Werner…
Pre- and post-selected measurements with coupling-strength-dependent modulation
Zhaoxue Li, Jiangdong Qiu, Xiaodong Qiu +7
Pre- and post-selected (PPS) measurement, especially the weak PPS measurement, is a useful protocol for amplifying small physical parameters. However, it is difficult to retain bot…
Monotonic quantum-to-classical transition enabled by positively-correlated biphotons
Rui-Bo Jin, Guo-Qun Chen, Hui Jing +4
Multiparticle interference is a fundamental phenomenon in the study of quantum mechanics.It was discovered in a recent experiment [Ra, Y.-S. et al, Proc. Natl Acad. Sci. USA \textb…
Bell's Nonlocality Can be Detected by the Violation of Einstein-Podolsky-Rosen Steering Inequality
Jing-Ling Chen, Changliang Ren, Changbo Chen +2
Recently quantum nonlocality has been classified into three distinct types: quantum entanglement, Einstein-Podolsky-Rosen steering, and Bell's nonlocality. Among which, Bell's nonl…
Indistinguishable single photons with flexible electronic triggering
Adetunmise C. Dada, Ted S. Santana, Ralph N. E. Malein +6
A key ingredient for quantum photonic technologies is an on-demand source of indistinguishable single photons. State-of-the-art indistinguishable single-photon sources typically em…
Optimal GHZ Paradox for Three Qubits
Changliang Ren, Hong-Yi Su, Zhen-Peng Xu +2
Quatum nonlocality as a valuable resource is of vital importance in quantum information processing. The characterization of the resource has been extensively investigated mainly fo…
Beating the Clauser-Horne-Shimony-Holt and the Svetlichny games with Optimal States
Hong-Yi Su, Changliang Ren, Jing-Ling Chen +6
We study the relation between the maximal violation of Svetlichny's inequality and the mixedness of quantum states and obtain the optimal state (i.e., maximally nonlocal mixed stat…
High-efficiency single-photon Fock state production by transitionless quantum driving
X. Shi, L. F. Wei
Single photon source is one of the key devices for optical quantum information processing. Differing from the usual stimulated Raman adiabatic passage to obtain single-photon radia…
