We shall revisit some basic ideas on quantum information and focus on entanglement as a needed ingredient for the speed-up of quantum algorithms. It is argued that quantum correlations pervade the physical systems at critical points. Entanglement scaling laws can be characterized using conformal symmetry. Entanglement loss controls renormalization group flows.
