    "abstract": "An attack on the ``Bennett-Brassard 84\u0027\u0027(BB84) quantum key-exchange protocol\nin which Eve exploits the action of gravitation to infer information about the\nquantum-mechanical state of the qubit exchanged between Alice and Bob, is\ndescribed. It is demonstrated that the known laws of physics do not allow to\ndescribe the attack. Without making assumptions that are not based on broad\nconsensus, the laws of quantum gravity, unknown up to now, would be needed even\nfor an approximate treatment. Therefore, it is currently not possible to\npredict with any confidence if information gained in this attack will allow to\nbreak BB84. Contrary to previous belief, a proof of the perfect security of\nBB84 cannot be based on the assumption that the known laws of physics are\nstrictly correct, yet.",
