| Abstract(in English) | In optical communication processes, the efficiency of information transmission increases in proportion to the energy of the input signals. Since it might be difficult to control infinite energy in actual physical systems, it can be considered that there exists an upper bound of information transmission. Therefore we introduce a method improving the efficiency of information transmission by using the control of the squeezing ratio of the control signals for the fixed energy of the input signals in optical communication processes. In this paper, we consider the efficiency of information transmission by means of the quantum mutual entropy and the quantum capacity for the optical communication process with the squeezed control process. |
