Abstract
The optical communication theory has been developed in the fields of both mathematics and engineering, and it has become very important recently. In this paper we mathematically treat quantum control communication processes from information theoretical points of view, and we derive error probabilities for a concrete quantum channel in each digital modulation and detection. In paticular, several error probabilities for a coherent state and a squeezed state are rigorously calculated. It is shown that a proper squeezed state provides us a lower error probability, namely, better efficiency for optical communication.
