The non-local, genuine quantum properties of quantum states of bi- und multipartite quantum systems will be investigated with respect to their possible importance for quantum informations processing. In particular, the mathematical structure of separable, or non-separable states will be studied both from the qualitative, as well as the quantitative point of view. New kinds of quantitative operational measures of entanglement will be proposed and characterized. The problem of experimental detection and characterization of entanglement will be addressed. The simular program of research will be applied to quantum operations.
