    "abstract": "The experimental determination of entanglement is a major goal in the quantum\ninformation field. In general the knowledge of the state is required in order\nto quantify its entanglement. Here we express a lower bound to the robustness\nof entanglement of a state based only on the measurement of the energy\nobservable and on the calculation of a separability energy. This allows the\nestimation of entanglement dismissing the knowledge of the state in question.",
