This book explores interesting possibilities of extracting information about quantum states from data readily obtained from experiments, such as tomograms and e

The term 'nonclassical states' refers to the quantum states that cannot be produced in the usual sources of light, such as lasers or lamps, rather than those re

The recent generation in the laboratory of phase squeezed and intensity squeezed light beams has brought to fruition the theoretical predictions of such non-cla
