AB This work describes the most important states used in the field of quantum information: coherentstates. We start with the definition of a Hamiltonian for a two-dimesional harmonic oscillatorfrom which we construct the eigenstates called Hermite-Gauss states and Laguerre-Gauss states,which allow to describe the modes of a beam system. We continue describing the main coherentand thermal states that can be defined from the same Hamiltonian, this time they are visualizedas eigenstates of the SU(1, 1) group generators and then for SU(2). Subsequently, a theoreticalsystem involving the input of a thermal state and an empty state in a beam splitter is discussedand experimentally compared.
