Conclusion
In this paper we numerically derived C 1 of the binary mixed state signal. The mutual informations of codeword states, I 2 and I 3, were calculated and were compared with C 1 and C. The expected amount of the superadditivity was given when the pure state preparation is too difficult in experimental set up.
