This chapter presents the basic principles of quantum optics. It starts from recalling the main elements of quantum mechanics in Heisenberg and Schroedinger interpretations, then the creation and annihilation operators are introduced, and bosonic and fermionic commutation rules are discussed. The secondary quantization theory is used to show differences between coherent, thermal, and Fock states of light; introduce squeezing and antisqueezing; and discuss the statistics of photons. Finally, the polarization and second-order coherence of light are discussed from the point of view of the quantum optics.

Keywords: Glauber; squeezing; secondary quantization; photon; quantum optics
