Information Quantities and Parameter Estimation in Classical Systems
For the study of quantum information theory, we require fundamental knowledge of information theory, mathematical statistics, and information geometry, which are mainly examined in a nonquantum context. This chapter briefly summarizes the fundamentals of these topics from a unified viewpoint. Since these topics are usually treated individually, this chapter will be useful even for a non-quantum applications.
