| Abstract: | The loss of a quantum channel leads to an irretrievable particle lossas well as information. In this paper, the loss of quantum channel isanalysed and a method is put forward to recover the particle andinformation loss effectively using universal quantum errorcorrection. Then a secure direct communication scheme is proposed,such that in a loss channel the information that an eavesdropper canobtain would be limited to arbitrarily small when the code isproperly chosen and the correction operation is properly arranged. |
