Geometric measure of entanglement compared to measures based on fidelity — •Alexander Streltsov — Heinrich-Heine-Universität Düsseldorf, Institut für Theoretische Physik III, Düsseldorf, Germany

One big problem in quantum information theory is the quantification of entanglement for multipartite mixed states. Different axiomatic and operational measures were proposed so far. In this work connections between the geometric measure of entanglement and measures based on the fidelity are established. Also a useful expression for fidelity is derived.
