|Title:||Characterization and quantification of symmetric Gaussian-state entanglement through a local classicality criterion|
|Author:||de Oliveira, MC|
|Abstract:||A necessary and sufficient condition for characterization and quantification of entanglement of any bipartite Gaussian state belonging to a special symmetry class is given in terms of classicality measures of one-party states. For Gaussian states whose local covariance matrices have equal determinants it is shown that separability of a two-party state and classicality of a one-party state are completely equivalent to each other under a nonlocal operation, allowing entanglement features to be understood in terms of any available classicality measure.|
