Abstract: Abstract Optimizing a signal detection process to minimize the error probability or to maximize the mutual information is one of the most interesting subject to implement super-reliable communication systems, quantum computers, etc [1–6]. The optimum detection operators which are the mathematical description of the optimum signal detection process have been derived for some signal quantum states in the case of the error probability [7, 8]. However, in the case of the maximum mutual information, the derivation of the optimum detection operators have been much difficult [9,10].
