Quantum States of Light
This book explains what quantum states of light look like. Of special interest, a single photon state is explained by using a wave picture, showing that it corresponds to the complementarity of a quantum. Also explained is how light waves are created by photons, again corresponding to the complementarity of a quantum. The author shows how an optical wave is created by superposition of a 'vacuum' and a single photon as a typical example. Moreover, squeezed states of light are explained as 'longitudinal' waves of light and Schrödinger's cat states as macroscopic superposition states.
