In this talk we present the experimental and theoretical analysis of vacuum-class two-mode squeezed states, i.e. of bi-partite continuous variable entangled states generated by mixing a squeezed mode with a vacuum mode at a 50:50 beam splitter. We observed one of the strongest Einstein-Podolsky-Rosen (EPR) correlations in the continuous variable regime. Theoretically we found that arbitrarily strong EPR correlations are possible with this scheme only depending on the optical loss and the input squeezing.
