Superconducting devices lie at the heart of quantum-optical circuits operating at microwave frequencies. They are also the technology of choice for single-photon detection at infrared wavelengths. Specialist reviews of sub-topics within these fields are available in the research literature, but this monograph is the first to bring the whole subject together in a single volume. As such, it provides an excellent overview of the present state of the art for postgraduate students and researchers entering the field.

The book is split into two parts focusing, respectively, on the detectors and the circuits, and the editors have assembled a strong team of contributors, with a good balance between the two topics. Overall, this is a very timely work, which should be of interest to a wide range of researchers in quantum-optical technologies.
