Abstract: The quantum entanglement is a quantum phenomenon occuring when pairs or groups of particles are generated or interact in ways such that the quantum state of each particle cannot be described independently of the others, even when the particles are separated by a very large distance. Their quantum state must be described for the system as a whole.The present paper is a short revue of EPR paradox subjected of a 1935 paper, Bells inequality published in 1964, and Alain Aspects experiment in 1982. Some metaphysical aspects are also discussed.

Keywords: quantum entanglement, EPR paradox, Bell’s inequality, Aspect’s experiment, hidden variable.
