What's Happening?
Recent research has explored the use of geometric diagrams to analyze Bell inequalities with multiple observables, focusing on local hidden variables (LHVs) theories. These theories suggest that measurement outcomes are predetermined, with physical influences limited to the speed of light. The study reveals that in even d-dimensional systems, the maximum number of delta functions that can simultaneously equal unity is three, as established by Theorem 1. This finding is significant in understanding quantum correlations and the classical upper bounds of Bell functions, which are crucial in quantum mechanics and information theory.
