Résumé

This book explains what quantum states of light look like. Moreover, squeezed states of light are explained as "longitudinal" waves of light and Schroedinger's cat states as macroscopic superposition states.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 Schroedinger's cat states as macroscopic superposition states.1.
