Improved lower and upper bounds for entanglement of formation
Xue-Na Zhu, Shao-Ming Fei
We provide analytical lower and upper bounds for entanglement of formation for bipartite systems, which give a direct relation between the bounds of entanglement of formation and c…

Lower Bound of Multipartite Concurrence Based on Sub-quantum State Decomposition
Xue-Na Zhu, Ming-Jing Zhao, Shao-Ming Fei
We study the entanglement of tripartite quantum states and provide analytical lower bound of concurrence in terms of the concurrence of sub-states. The lower bound may improve all…

Lower Bounds of Concurrence for Multipartite States
Xue-Na Zhu, Ming Li, Shao-Ming Fei
We study the entanglement of multipartite quantum states. Some lower bounds of the multipartite concurrence are reviewed. We further present more effective lower bounds for detecti…
