    "abstract": "We propose the Entanglement Potential (EP) as a measure of nonclassicality\nfor quantum states of a single-mode electromagnetic field. It is the amount of\ntwo-mode entanglement that can be generated from the field using linear optics,\nauxiliary classical states and ideal photodetectors. The EP detects\nnonclassicality, has a direct physical interpretation, and can be computed\nefficiently. These three properties together make it stand out from previously\nproposed nonclassicality measures. We derive closed expressions for the EP of\nimportant classes of states and analyze as an example the degradation of\nnonclassicality in lossy channels.",
