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 corr

Appendix A: Semiclassical approximation

Quantum information describes the new field which bridges quantum physics and information science. The quantum world allows for completely new architectures and

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

Covering some of the most exciting trends in quantum optics - quantum entanglement, teleportation, and levitation - this textbook is ideal for advanced undergra
