    "abstract": "The model of the quantum protocols sealing a classical bit is studied. It is\nshown that there exist upper bounds on its security. For any protocol where the\nbit can be read correctly with the probability $\\alpha $, and reading the bit\ncan be detected with the probability $\\beta $, the upper bounds are $% \\beta\n\\leqslant 1/2$ and $\\alpha +\\beta \\leqslant 9/8$.",
