Title: Quantification of continuous variable entanglement with only two types of simple measurements
Author: Rigolin, G
de Oliveira, MC
Abstract: Here we propose an experimental set-up in which it is possible to obtain the entanglement of a two-mode Gaussian state, be it pure or mixed, using only simple linear optical measurement devices. After a proper unitary manipulation of the two-mode Gaussian state only number and purity measurements of just one of the modes suffice to give us a complete and exact knowledge of the state's entanglement.
