Abstract

The principle of complementary, which describes the wave-particle duality of quanta, is one of the cornerstones of modern quantum theory. An experiment is described in which the quantified principle of complimentary is demonstrated for a variety of input quantum states, including mixed states. The direct quantum state is directed into a Mach-Zender interferometer with 50-50 beam splitters. In one of the arm of the interferometer various optical elements are used to modify the polarization of the light in that arm. This in turn affects the observable visibility. To produce general mixed state, one can generate the circumstance where no interference is observed, despite that the polarization cannot yield which-path information.
