    • Abstract

       

      On the face of some recent experiments claiming the simultaneous presence of both `sharp interference' and `highly reliable which way information' and some others casting light on the origin of complementarity in quantum interferometric experiments, the whole issue is reviewed on the basis of our earlier precise formulation of Bohr's complementarity principle. It is pointed out that contradicting the principle (in this specific formulation) is impossible without contradicting quantum mechanics and a lack of general consensus regarding the origin of the mutual exclusiveness is at the root of the controversy and confusions.
