    "abstract": "A powerful theoretical structure has emerged in recent years on the\ncharacterization and quantification of entanglement in continuous-variable\nsystems. After reviewing this framework, we will illustrate it with an original\nset-up based on a type-II OPO with adjustable mode coupling. Experimental\nresults allow a direct verification of many theoretical predictions and provide\na sharp insight into the general properties of two-mode Gaussian states and\nentanglement resource manipulation.",
