    "abstract": "We review the status of Bell\u0027s inequalities in quantum information, stressing\nmainly the links with quantum key distribution and distillation of\nentanglement. We also prove that for all the eavesdropping attacks using one\nqubit, and for a family of attacks of two qubits, acting on half of a maximally\nentangled state of two qubits, the violation of a Bell inequality implies the\npossibility of an efficient secret-key extraction.",
