| Outline of Final Research Achievements |
A half-century has passed after studies of quantum communication began. Now we dream the day that quantum communication systems are used everyday. To achieve the goal, we should study all kinds of subjects which contain not only popular issues but also sober or more realistic ones. One of such issues is a quantum fading channel which is essential in wireless quantum communications.
In this study, we consider a channel model of a quantum fading and show performance of quantum communication systems when we apply various coding-decoding, and modulation. As a result, quantum receivers clearly outperform classical ones under the fading environment.
