A Note on Entanglement of Formation and Generalized Concurrence
arXiv:quant-ph/0408131 · doi:10.1016/j.physleta.2004.07.030
Abstract
We discuss a kind of generalized concurrence for a class of high dimensional quantum pure states such that the entanglement of formation is a monotonically increasing convex function of the generalized concurrence. An analytical expression of the entanglement of formation for a class of high dimensional quantum mixed states is obtained.
