Using Marylou to Characterize States That Can Violate Bell’s Inequality
Bell’s inequality provides a theoretical test for local realism in nature. Experimental tests of this inequality have been carried out and show beyond reasonable doubt that local realism is incompatible with a quantum mechanical description of nature. Certain quantum states have the capacity to violate Bell’s inequality, while others never can. What are the characteristics that set these states apart? I study the Clauser-Horne-Shimony-Holt (CHSH) inequality, a variation of Bell’s inequality, and outline my attempts to characterize the states which can violate it. As an alternative to symbolic analysis and linear algebra as solutions to this problem, I discuss use of numerical solution with BYU’s FSL Supercomputer (Marylou).
