    "abstract": "In the well known treatment of quantum teleportation, the receiver should\nconvert the state of his EPR particle into the replica of the unknown quantum\nstate by one of four possible unitary transformations. However, the importance\nof these unitary transformations must be emphasized. We will show in this paper\nthat the receiver can not transform the state of his particle into an exact\nreplica of the unknown state which the sender want to transfer if he have not a\nproper implementation of these unitary transformations. In the procedure of\nconverting state, the inevitable coupling between EPR particle and environment\nwhich is needed by the implementation of unitary transformations will reduce\nthe accuracy of the replica.",
