Abstract

In this presentation I discuss the implications of the recent experiment by Ou et al.¹ This experiment is the first realization of the gedanken experiment considered by Einstein, Podolsky, and Rosen² (EPR) in 1935 as an argument for the incompleteness of quantum mechanics. I conclude that the Ou et al. realization of the EPR experiment suggests that there exists an even stronger paradox than that of EPR. Either: 1. We reject macroscopic local realism, where macroscopic local realism will be defined in this paper; or; 2. Accepting macroscopic local realism, we must accept as a consequence that quantum mechanics is incomplete.
