    "abstract": "Here we propose an experimental set-up in which it is possible to measure the\nentanglement of a two-mode Gaussian state, be it pure or mixed, using only\nsimple linear optical devices. After a proper unitary manipulation of the\ntwo-mode Gaussian state only number and purity measurements of just one of the\nmodes suffice to give us a complete and exact knowledge of the state\u0027s\nentanglement.",
