| Research Abstract |
In quantum communication theory, the broadband channel capacity, which was derived recently, is not just a capacity of a channel with a broad band width but the ultimate information carrying limit. In this research, in order to clarify how to achieve the ultimate limit, we show performance of quantum communication systems when we apply various coding-decoding, modulation, and multiplexing. As a result, it is clarified that there is the case that the capacity is almost achieved by using the optical region only.
