Curs: 2021-2022. Tutors: José María Gómez Cama, Bruno Juliá-DíazIn this thesis we build and characterize a portable experimental setup to perform a Bell test using the CHSH Bell inequality with polarization-entangled photons. These photons are produced using Type-I Spontaneous Parametric Down-Conversion with two BBO crystals. We study the theory behind the CHSH Bell inequality, and the mechanism of Spontaneous Parametric Down-Conversion and compare a Hidden Variable Theory to Quantum Theory29 p.application/pdfengcc-by-nc-nd (c) Jaramillo, 2022http://creativecommons.org/licenses/by-nc-nd/3.0/es/Teorema de BellTeoria de variables ocultesEntrellaçament quànticTreballs de fi de màsterBell's theoremHidden-variable theoryQuantum entanglementMaster's thesesinfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/openAccess
