    "abstract": "The purpose of this short tutorial paper is to review various criteria that\nhave been used to characterize the quantum character of correlations in optical\nsystems, such as \"gemellity\", QND correlation, intrication, EPR correlation and\nBell correlation, to discuss and compare them. This discussion, restricted to\nthe case of measurements of continuous optical variables, includes also an\nextension of known criteria for \"twin beams\" to the case of imbalanced\ncorrelations.",
