Alongside a thorough definition of basic concepts andtheir interrelations, backed by numerous examples, this textbookfeatures a rare discussion of quantum mechanics and informationtheory combined in one text. It deals with important topics hardlyfound in regular textbooks, including theRobertson–Schrödinger relation, incompatibility between angleand angular momentum, ???dispersed indeterminacy???,interaction–free measurements, ???submissive quantummechanics???, and many others. With its in–depth discussion ofkey concepts complete with problems and exercises, this book ispoised to become the standard textbook for advanced undergraduateand beginning graduate quantum mechanics courses and an essentialreference for physics students and physics professionals.
