Maziero, L. C. Céleri, R. M. Serra, and V. Vedral<br/>Recently some authors have pointed out that there exist nonclassical correlations which are more general, and possibly more fundamental, than entanglement. For these general quantum correlations and their classical counterparts, under the action of decoherence, we identify three general types of dyn...<br/>[Phys. Rev.
