Abstract

Complementarity is one of the most basic principles of Quantum Mechanics Quantum mechanical object, be it a photon or a massive particle, shows position (particle-like) or momentum (wave-like) attributes exclusively depending on the experimental situation Over the years, Young’s two-slit experiment has been emphasized as a good example of complementarity We report a set of two-slit experiments in which complementarity is enforced by availability of which-path information at the measurement stage of the quantum.
