Quantum Entanglement

National Institute for Research & Development in Informatics, ICI Bucharest

Abstract: Entanglementul cuantic este un fenomen cuantic care apare atunci când două sau mai multe particule cuantice sunt generate sau interacţionează astfel încât  starea cuantică a fiecărei particule nu mai poate fi descrisă independent de celelalte, chiar dacă acestea sunt separate spaţial la distanţe foarte mari. Starea lor cuantică este descrisă mai degrabă ca un întreg. Lucrarea de faţă este un scurt rezumat a paradoxului EPR elaborat în 1935, inegalităţile lui Bell publicate în 1964 şi experimentul lui Alain Aspect din 1982. De asemenea sunt discutate unele aspecte metafizice.

Keywords: entanglement cuantic, paradoxul EPR, inegalităţile lui Bell, experimentul lui Aspect, variabile ascunse.
