Furusawa A. Quantum States of Light

Springer Japan, 2015 — 104p. — (SpringerBriefs in Mathematical Physics 10) — ISBN: 978-4-431-55960-3 (eBook), 978-4-431-55958-0 (Softcover).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.Quantum States of Light
