A matter wave Rarity-Tapster interferometer to demonstrate non-locality
Abstract
We present an experimentally viable approach to demonstrating quantum non-locality in a matter wave system via a Rarity-Tapster interferometer using two -wave scattering halos generated by colliding helium Bose-Einstein condensates. The theoretical basis for this method is discussed, and its suitability is experimentally quantified. As a proof of concept, we demonstrate an interferometric visibility of , corresponding to a maximum CSHS-Bell parameter of , for the Clauser-Horne-Shimony-Holt (CHSH) version of the Bell inequality, between atoms separated by correlation lengths. This constitutes a significant step towards a demonstration of a Bell inequality violation for motional degrees of freedom of massive particles and possible measurements of quantum effects in a gravitationally sensitive system.
