Some remarks on Bell's Inequality tests
arXiv:quant-ph/0212060 · doi:10.1209/epl/i2003-00333-0
Abstract
We emphasize the difficulties of an experiment that can definitely discriminate between local realistic hidden variables theories and quantum mechanics using the Bell CHSH inequalities and a real measurement apparatus. In particular we analyze some examples in which the noise in real instruments can alter the experimental results, and the nontrivial problem to find a real "fair sample" of particles to test the inequalities.
