Quantum theory is considered as the most successful scientific theory of all time. However, the understanding1 and interpretation of quantum theory has been subjected to a continuous debate since its formulation. A leading role was played by Einstein in the development of the old quantum theory but he was not impressed by the statistical interpretation of the quantum theory. He believed in a world of well defined law and order in which objectivity exists. He never thought that the new quantum theory as a complete theory. In 1926 in a letter to Max Born, Einstein wrote: Quantum mechanics is very impressive. ... The theory produces good deal but hardly brings us closer to the secret of the old one. I am at all events convinced that God does not play dice.
