Correlations and the quantum-classical border — •Dagmar Bruß¹, Alexander Streltsov², and Hermann Kampermann¹ — ¹Institut für Theoretische Physik III, Universität Düsseldorf, Germany — ²ICFO, Castelldefels (Barcelona), Spain

There are several options to define the quantum-classical border for states of composite systems: First, classicality can be viewed as locality in the sense that all Bell-type inequalities are fulfilled; second, it can be defined via the possibility to create the state with local operations and classical communication; and third, via the existence of a local Hamiltonian that leaves the state invariant. Once we agree on where to draw the quantum-classical border, some counterintuitive phenomena near this border will be illustrated.
