This follows from Bell’s theorem by showing the measurement statistics of the EPR-experiment can never be fully reproduced by any local hidden variable model (LHV-model). Research has been done in the last couple of decades into the degree to which LHV-models can reproduce measurement statistics approximating the EPR’s statistics. Specifically of interest is finding which amplitudes can be reproduced by LHV-models with an exact correlation. Our analysis and the literature take into consideration: a density matrix separability criterion on the two-electron singlet state, constructs by Kaszlikowski and Zukowski, and the Grothendieck constant. Further, open question arise and new approaches to the locality of quantum states are given.Show less
