Entanglement
Entanglement was defined by Schrodinger the characteristic trait of quantum mechanics, and indeed it represents one of the most peculiar properties of quantum systems. After having been the source of a long debate among theorists interested in the foundations of quantum mechanics, in the last decades a sequence of experiments, in particular with photons, led, on the one hand, to test the validity of standard quantum mechanics with respect to alternative theories (Bell inequalities) and, on the other hand, paved the way to new technologies, the so-called second quantum revolution. This line of research was awarded this year with the assignment of Nobel prize to Aspect, Clauser and Zeilinger. In this talk, I will describe what entanglement is and present the main experiments that contributed to this fascinating line of research in quantum optics.
