Polygamy relation of quantum correlations with equality
Zhi-Xiang Jin, Bing Yu, Xue-Na Zhu +2
We provide a generalized definition of polygamy relations for any quantum correlation measures. Instead of the usual polygamy inequality, a polygamy relation with equality is given…
A Universal Quantum Certainty Relation for Arbitrary Number of Observables
Ao-Xiang Liu, Ma-Cheng Yang, Cong-Feng Qiao
We derive by lattice theory a universal quantum certainty relation for arbitrary observables in -dimensional system, which provides a state-independent maximum lower bound o…
Test of macroscopic realism with coherent light
Hui Wang, Shuang Wang, Cong-Feng Qiao
Macro-realism is a fundamental feature of classical world that contradicts with the quantum theory. An elegant method of testing macrorealism is to apply the Leggett-Garg inequalit…
Probing a hybrid channel for the dynamics of non-local features
Atta ur Rahman, S. M. Zangi, Ma-Cheng Yang +1
Effective information transmission is a central element in quantum information protocols, but the quest for optimal efficiency in channels with symmetrical characteristics remains…
Concurrence triangle induced genuine multipartite entanglement measure
Zhi-Xiang Jin, Yuan-Hong Tao, Yao-Ting Gui +3
We study the quantification of genuine multipartite entanglement (GME) for general multipartite states. A set of inequalities satisfied by the entanglement of -partite pure stat…
General Schemes for Quantum Entanglement and Steering Detection
Ma-Cheng Yang, Cong-Feng Qiao
Separability problem is a long-standing tough issue in quantum information theory. In this paper, we propose a general method to detect entanglement via arbitrary measurement $\bol…
Informationally complete measures of quantum entanglement
Zhi-Xiang Jin, Shao-Ming Fei, Xianqing Li-Jost +1
Although quantum entanglement has already been verified experimentally and applied in quantum computing, quantum sensing and quantum networks, most of the existing measures cannot…
Generalized Wigner-Yanase Skew Information and the Affiliated Inequality
Ma-Cheng Yang, Cong-Feng Qiao
A family of skew information quantities is obtained, in which the well-known Wigner-Yanase skew information and quantum Fisher information stand as special cases. A transparent pro…
A new parameterized monogamy relation between entanglement and equality
Zhi-Xiang Jin, Shao-Ming Fei, Xianqing Li-Jost +1
We provide a generalized definition of the monogamy relation for entanglement measures. A monogamy equality rather than the usual inequality is presented based on the monogamy weig…
Leggett-type inequalities for testing nonlocal realism in multipartite systems
Abdul Sattar Khan, Ma-Cheng Yang, Cong-Feng Qiao
Nonlocal realism represents the last classical cornerstone in conflict with quantum theory, and has been shown to be largely untenable in bipartite systems [Nature 446, 871 (2007);…
An Effective Way of Characterizing the Quantum Nonlocality
Ma-Cheng Yang, Jun-Li Li, Cong-Feng Qiao
Nonlocality is a distinctive feature of quantum theory, which has been extensively studied for decades. It is found that the uncertainty principle determines the nonlocality of qua…
