    "abstract": "The principles are elaborated which underlie the applications of general\nnonclassical states to communication and measurement systems. Relevant\nclassical communication concepts are reviewed. Communication and measurement\nprocesses are compared. The possible advantages of nonclassical states in\nclassical information transfer are assessed. The significance of novel quantum\namplifiers and duplicators in communication is emphasized. A general approach\nis developed for determining the ultimate accuracy limit in quantum measurement\nsystems. It is found that bandwidth or mode number is a most important\nparameter and ultrahigh precision measurement is possible in systems with a\nfixed energy but many modes. The problem of the standard quantum limit in\nmonitoring the position of a free mass is also addressed.",
