    "abstract": "Relativistic quantum field theory imposes additional fundamental restrictions\non the distinguishability of quantum states. Because of the unavoidable\ndelocalization of the quantum field states in the Minkowski space-time, the\nreliable (with unit probability) distinguishability of orthogonal states\nformally requires infinite time. For the cryptographic protocols which are\nfinite in time the latter means that the effective ``noise\u0027\u0027 is present even in\nthe ideal communication channel because of the non-localizability of the\nquantum field states.",
