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…
