Epr Pair

Within the framework of relativistic quantum theory, we consider the Einstein-Podolsky-Rosen (EPR) gedanken-experiment in which measurements of the spin are performed by moving observers. We find that the perfect anti-correlation in the same direction between the EPR pair no longer holds in the observers' frame. This does not imply a breakdown of the non-local correlation. We explicitly show that the observers must measure the spin in appropriately chosen different directions in order to observe the perfect anti-correlation. This fact should be taken into account in utilizing the entangled state in quantum communication by moving observers.

This presentation is a suggestion for rethinking future inquiry in information studies. Features of quantum theory, including examining information and informing action as non-local, dynamic, and time-reversible allow for a departure from existing intellectual constraints. The result desired would be a renaissance in the examination of complex processes, examination not limited by past materialist, instrumentalist, and static conceptions.Cette communication propose une nouvelle façon de penser un questionnement futur en science de l’information. Des notions de théorie quantique, y compris examiner l’information et éclairer les interventions dans une optique non locale, dynamique et réversible permettent de s’éloigner des contraintes intellectuelles actuelles. Le résultat souhaité serait une renaissance de l’examen de processus complexes, non limité aux anciennes conceptions matérialistes, instrumentalistes et statiques.

Hardy's non-locality theorem for multiple two-level systems is explored in the context of generalized non-local theory. We find non-local but non-signaling probabilities satisfying Hardy's argument for two two-level and three two-level systems. Maximum probability of success of Hardy's argument is obtained for three two-level systems in quantum theory as well as in a more generalized theory. Interestingly, the maximum in the generalized non-local theory for both the two two-level systems and three two-level systems turns out to be the same.
