… a loophole-free violation of local realism using entangled photon pairs. We ensure that all
relevant events in our Bell test … Using a hypothesis test, we compute p values as small as 5.9 × …

… In the following sections, we experimentally demonstrate a loophole-free Hardy constrained
… a paradox against local realistic theories. Experiments—The present Hardy,s paradox test is …

… for an experimenter that wants to perform a loophole-free experimental test. … We must
determine how strong the evidence is against local realism, given our finite-sized sample of …

… In the language of strong Bell tests, this conditional relation … such freedom within local realism,
the tests must assume … could only be explained within local realism if events across history …

… local realistic explanations for their observations. In 2015, three experiments took place
that tested local realism … data show a strong violation of local realism and strong support for …

… a small fraction of trials are randomly selected as test trials for the loopholefree Bell test, but
the security of an information task based on other trial results is guaranteed. We quantify the …

… We present a loophole-free violation of local realism using entangled photon pairs. We
ensure that all relevant events in our Bell test are spacelike separated by placing the parties far …

… local realist, hiddenvariables theory. Although Grete Hermann had raised strong objections
to von Neumann’s proof, … ’s proof was flawed: a sufficient condition for local realism had been …

… in terms of local realism. In this work, we present an experiment which simultaneously closes
… To understand more precisely what is required to implement a loophole-free Bell test, we …

… Similarly the formula (4) shows that a loophole free experiment in which a violation of Bell’s
inequalities will be observed is impossible if the distance between detectors is large enough. …
