Three-region vacuum nonlocality
Abstract
Description
The correlations between three arbitrarily far-apart regions of the vacuum state of the free Klein-Gordon field are investigated by means of its finite duration coupling to three localized detectors. It is shown that these correlations cannot be reproduced in terms of a hybrid local-nonlocal hidden-variable model, i.e., the correlations between three arbitrarily separated regions of the vacuum are fully nonlocal.
