The book’s core philosophy is to make quantum principles intuitive and accessible. It navigates the complexities of the subject by focusing on conceptual understanding and practical application, rather than getting lost in overly dense mathematical formalism. It is written for the computer scientist and engineer, translating the principles of quantum mechanics into the language of information security.
