    "abstract": "We present a notion of generalized entanglement which goes beyond the\nconventional definition based on quantum subsystems. This is accomplished by\ndirectly defining entanglement as a property of quantum states relative to a\ndistinguished set of observables singled out by Physics. While recovering\nstandard entanglement as a special case, our notion allows for substantially\nbroader generality and flexibility, being applicable, in particular, to\nsituations where existing tools are not directly useful.",
