| Abstract(in English) | The beam wandering is an inherent effect in wireless quantum communication and is considered to be a kind of fading effect. These are modeled as a probabilistic attenuated channel that transmissivity in attenuated channel is probabilistic. The Kraus representation is famous and useful as the mathematical description of the quantum channel and has been derived only a qubit system for the probabilistic attenuated channel. In the present paper, we consider the derivation of the Kraus representation with Choi matrix of the probabilistic attenuated channel in a multi-dimensional system. |
