Abstract

This paper presents an experiment suitable for advanced undergraduate students. We use polarization-entangled photon pairs in order to demonstrate quantum nonlocality. The entangled state is created by spontaneous parametric downconversion using a violet laser diode and nonlinear BBO-II crystals. The idea behind Bell's inequality is commented, and finally a test of the Clauser, Horne, Shimony, and Holt version of the Bell inequality is performed, finding $S=-2.32\pm 0.045$ contradicting the hidden variables theories prediction. This experimental setup takes less than a few hours to be ready, while the data collection takes no more than ten minutes.
