It has been shown that the electric field of a coherent state resembles the classical solution of Maxwell equations. The phase of a coherent state has been studied, showing that in the asymptotic limit of average photon numbers, a coherent state has a well-defined phase. Finally, the squeezed state of the vacuum has been studied, showing it is related to the Lie group SU(1,1), both for 1 and 2 modes of oscillation, and has a smaller uncertainty in one of the quadratures than a coherent state.8 p.application/pdfengcc-by-nc-nd (c) Pont, 2025http://creativecommons.org/licenses/by-nc-nd/3.0/es/Estat coherentIncertesaTreballs de fi de grauCoherent stateUncertaintyBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
