In a Bell experiment, it is natural to seek a causal account of correlations wherein only a common cause acts on the outcomes. For this causal structure, Bell inequality violations can be explained only if causal dependencies are modelled as intrinsically quantum. There also exists a vast landscape of causal structures beyond Bell that can … Continua a leggere
This year the Nobel prize goes to Alain Aspect, John Francis Clauser and Anton Zeilinger celebrating the power of quantum mechanics. They have been recognized as the pioneering scientists which realized the first “experiments with entangled photons, establishing the violation of Bell inequalities” and therefore have been awarded by the Royal Swedish Academy of Sciences. … Continua a leggere
Quantum teleportation is one of the most striking consequences of quantum mechanics and is defined as the transmission and reconstruction of an unknown quantum state over arbitrary distances. This concept was introduced for the first time in 1993 by Charles Bennett and coworkers, it has then been experimentally demonstrated by several groups under different conditions … Continua a leggere
A joint paper between Sapienza, International Institute of Physics and Perimeter Institute on the observation of genuine nonlocality in a triangle network has been published in PRX Quantum! Quantum networks are the center of many of the recent advances in quantum science, not only leading to the discovery of new properties in the foundations of quantum theory but … Continua a leggere
