Experimental Bell-inequality violation without the postselection loophole

G. Lima, Giuseppe Vallone, Andrea Chiuri, Adán Cabello, Paolo Mataloni

Abstract

We report on an experimental violation of the Bell-Clauser-Horne-Shimony-Holt (Bell-CHSH) inequality using energy-time-entangled photons. The experiment is not free of the locality and detection loopholes but is the first violation of the Bell-CHSH inequality using energy-time entangled photons which is free of the postselection loophole described by Aerts et al. [Phys. Rev. Lett. 83, 2872 (1999)].
