Non-Gaussian states by conditional measurements

Abstract

We address realistic schemes for the generation of non-Gaussian states of\nlight based on conditional intensity measurements performed on correlated\nbipartite states. We consider both quantum and classically correlated states\nand different kind of detection, comparing the resulting non Gaussianity\nparameters upon varying the input energy and the detection efficiency. We find\nthat quantum correlations generally lead to higher non Gaussianity, at least in\nthe low energy regime. An experimental implementation feasible with current\ntechnology is also suggested.\n
