Multiphoton Coherent States and the Linear Superposition Principle
Igor Jex, Vladimír Bužek · Journal of Modern Optics · 1993
We show that multiphoton coherent states can be expressed as linear quantum superpositions of a finite number of generalized coherent states. Quantum interferences between component states lead to appearance of non-classical effects such as oscillations in the photon number distribution, quadrature squeezing, SU(1, 1) squeezing and others.
