Conditional Entanglement
Dong Yang, Michal Horodecki, Z. D. Wang
abstract: Based on the ideas of {\it quantum extension} and {\it quantum conditioning},
we propose a generic approach to construct a new kind of entanglement measures
called {\it conditional entanglement}. The new measures, built from the known
entanglement measures, are convex, automatically {\it super-additive}, and even
smaller than the regularized versions of the generating measures. More
importantly, new measures can also be built directly from measures of
correlations, enabling us to introduce an {\it additive} measure and generalize
it to a multipartite entanglement measure.
