Abstract: Two quantum correlations Q and $$Q_\mathcal P$$QP for $$(m+n)$$(m+n)-mode continuous-variable systems are introduced in terms of average distance between the reduced states under the local Gaussian positive operator-valued measurements, and analytical formulas of these quantum… read more here.

Abstract: We propose a measure of nonclassical correlation [Formula: see text] in terms of local Gaussian unitary operations based on square of the fidelity [Formula: see text] for bipartite continuous-variable systems. This quantity is easier to… read more here.
