Characterizing multiparticle entanglement

Otfried Guehne

par Pierre Pujol - 8 février 2011

Entanglement is a valuable resource in quantum information processing and many experiments nowadays aim at the generation of entanglement between several particles. In this talk, I present some results on the characterization of multiparticle entanglement. First, I will discuss how entanglement can be detected with a high statistical significance. This is relevant for multi-photon experiments, since there the count rates are small. Second, I will investigate how different classes of entanglement can be distinguished. Finally, I will present an approach to characterize multiparticle quantum correlations using semidefinite programming.
