Abstract
We present an experimental test of the Clauser-Horne-Shimony-Holt Bell inequality on photon pairs in a
maximally entangled state of polarization in which a value S = 2.82759 ± 0.00051 is observed. This value comes close to the Tsirelson bound of |S|≤ 2 Sqrt(2), with S −2 Sqrt(2) =0.00084 ± 0.00051. It also violates
the bound |S| ≤ 2.82537 introduced by Grinbaum by 4.3 standard deviations. This violation allows us to exclude that quantum mechanics is only an effective description of a more fundamental theory.
