Comparisons of experimental entanglement witnesses and measures for a two-qubit system

ORAL

Abstract

A single operator cannot measure the entanglement for a general state; however, knowledge of the density matrix enables computation of any universal entanglement measure. Several entanglement witnesses have been proposed for two-qubit systems. We compare these to published measures.
