| We shall discuss the central role played in the quantum information theory by entanglement. A generalized version of Bell's theorem will be presented, as well as methods in multiphoton interferometry to obtain correlations violating the Bell inequalities. Finally, we shall present some quantum informational applications of entanglement. |
