Experimental realization of a first test of de Broglie Bohm theory

Abstract

De Broglie - Bohm (dBB) theory is a deterministic theory, built for\nreproducing almost all Quantum Mechanics (QM) predictions, where position plays\nthe role of a hidden variable. It was recently shown that different coincidence\npatterns are predicted by QM and dBB when a double slit experiment is realised\nunder specific conditions and, therefore, an experiment can test the two\ntheories. In this letter we present the first realisation of such a double slit\nexperiment by using correlated photons produced in type I Parametric Down\nConversion. Our results confirm QM contradicting dBB predictions.\n
