    "abstract": "We present a new measure of entanglement for mixed states. It can be\napproximately computable for every state and can be used to quantify all\ndifferent types of multipartite entanglement. We show that it satisfies the\nusual properties of a good entanglement quantifier and derive relations between\nit and other entanglement measures.",
