  "comment": "In this paper the correct calculations of the mutual information of the whole transmission, the quantum bit error rate (QBER) are presented. Mistakes of the general conclusions relative to the mutual information, the quantum bit error rate (QBER) and the security in W\\'{o}jcik's paper [Phys. Rev. Lett. {\\bf 90}, 157901(2003)] have been pointed out. Also I hope experts can give me some help in addressing the question I present in this paper",
