Information theory is central to computer science, and it is important in quantum computing. The topic of information theory was introduced by Claude Shannon in his 1948 paper, “A Mathematical Theory of Communication.” Shannon was primarily concerned with signal processing, data compression, and related topics. However, the field of information theory has grown since then. The focus of information theory is quantifying and communicating information. The field of information theory is closely ...
