Improved lower and upper bounds for entanglement of formation [PDF]
Xue-Na Zhu, Shao-Ming FeiWe 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 concurrence, and improve the previous results. Detailed examples are presented.View original: http://arxiv.org/abs/1211.0464
