Entanglement, Locality, and Hidden Variables The purpose of this paper is to provide an analysis of entanglement and the particular problems it poses for some physicists. In addition to looking at the history of entanglement and non-locality, this paper will use the Bell Test as a means for demonstrating how entanglement works, which measures the behavior of electrons whose combined internal angular momentum is zero. This paper will go over Dr. Bell's famous inequality, which shows why the process of entanglement cannot be explained by traditional means of local processes. Entanglement will be viewed initially through the Copenhagen Interpretation, but this paper will also look at two particular models of quantum mechanics, de-Broglie Bohm theory and Everett's Many-Worlds Interpretation, and observe how they explain the behavior of spin and entangled particles compared to the Copenhagen Interpretation.autWood, Keaten LawrencethsFoy, JosephdgcHines, TaylorctbDepartment of PhysicsctbSchool of Mathematical and Statistical SciencesctbBarrett, The Honors Collegeenghttps://hdl.handle.net/2286/R.I.6335139 pages116182906651628716197148341klwood2In Copyright2021-05TextEntanglementQuantum MechanicsBell's Inequalitymany-worlds interpretationde-Broglie Bohm theory
