Abstract:
By investigating the convex property of the function R, appeared in
computing the entanglement of formation for isotropic states in
Phys. Rev. Lett. 85, 2625 (2000), and
a tight lower bound of entanglement of formation
for arbitrary bipartite mixed states in
Phys. Rev. Lett. 95, 210501 (2005), we show analytically
that the very nice results in these papers are valid not only for
dimensions 2 and 3 but any dimensions.
