Quantifying entanglement resources
Christopher Eltschka, Jens Siewert · Journal of Physics A Mathematical and Theoretical · 2014
We present an overview of the quantitative theory of single-copy entanglement in finite-dimensional quantum systems. In particular we emphasize the point of view that different entanglement measures quantify different types of resources which leads to a natural interdependence of entanglement classification and quantification. Apart from the theoretical basis, we outline various methods for obtaining quantitative results on arbitrary mixed states.
