Volovich as part of Quantum Optics and Related Topics\n\n\nAbstract \nThe standard derivation of Bell-type inequality violations is typically applied only to scenarios involving short distances between detectors. Thi s conventional approach often overlooks the dependence of quantum mechanic al wave functions on space-time variables. In this study\, we examine the behavior of entangled photons produced in spontaneous parametric downconve rsion (SPDC) experiments and demonstrate that Bell-CHSH inequalities are n ot violated at large distances. We analyze the propagation of entangled ph oton wave packets and show that these initially entangled states tend to d isentangle over large spacelike separations. This finding aligns with the observed violations of Bell inequalities at shorter detector separations. To further explore this phenomenon\, we propose an experiment to investiga te how the quantum correlation function and Bell values change with increa sing detector distance\, predicting that these quantities will decrease in versely with distance.\nOn the absence of violation of Bell-CHSH inequalit ies at large distances.\n LOCATION:https://researchseminars.org/talk/QOART/40/ END:VEVENT END:VCALENDAR
