Constructing positive maps from block matrices
Yu Guo, Heng Fan
Positive maps are useful for detecting entanglement in quantum information theory. Any entangled state can be detected by some positive map. In this paper, the relation between pos…
Measurement-induced nonlocality over two-sided projective measurements
Yu Guo
Measurement-induced nonlocality (MiN), introduced by Luo and Fu [Phys. Rev. Lett. 106(2011)120401], is a kind of quantum correlation that beyond entanglement and even beyond quantu…
Entanglement detection beyond the CCNR criterion for infinite-dimensions
Yu Guo, Jinchuan Hou
In this paper, in terms of the relation between the state and the reduced states of it, we obtain two inequalities which are valid for all separable states in infinite-dimensional…
Concurrence for infinite-dimensional quantum systems
Yu Guo, Jinchuan Hou, Yuncai Wang
Concurrence is an important entanglement measure for states in finite-dimensional quantum systems that was explored intensively in the last decade. In this paper, we extend the con…
