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…
The RCCN criterion of separability for states in infinite-dimensional quantum systems
Yu Guo, Jinchuan Hou
In this paper, the realignment criterion and the RCCN criterion of separability for states in infinite-dimensional bipartite quantum systems are established. Let and be…
Positive finite rank elementary operators and characterizing entanglement of states
Xiaofei Qi, Jinchuan Hou
In this paper, a class of indecomposable positive finite rank elementary operators of order are constructed. This allows us to give a simple necessary and sufficient criter…
