New considerations on the separability of very noisy mixed states and implications for NMR quantum computing

Autor: Bulnes, J. D., Sarthour, R. S., de Azevedo, E. R., Bonk, F. A., Freitas, J. C. C., Guimarães, A. P., Bonagamba, T. J., Oliveira, I. S.

We revise the problem first addressed by Braunstein and co-workers (Phys. Rev. Lett. {\bf 83} (5) (1999) 1054) concerning the separability of very noisy mixed states represented by general density matrices with the form $\rho_\epsilon = (1-\epsilon)M
