A coherent introduction to key areas of ghost imaging and quantum lithography, the book presents the core principles needed to fully understand quantum imaging. It discusses the complementary sciences of ghost imaging and quantum lithography. Written for a broad audience of scientists and engineers working in academia and industry, the book gives complete coverage of the formalisms and experimental structure of each technology and presents material on the "non-quantum" alternatives to true quantum imaging. Each section concludes with a critical discussion on the challenges to practical application of quantum technologies in industry.
