    "abstract": "We have experimentally demonstrated the interferometric complementarity,\nwhich relates the distinguishability $D$ quantifying the amount of which-way\n(WW) information to the fringe visibility $V$ characterizing the wave feature\nof a quantum entity, in a bulk ensemble by Nuclear Magnetic Resonance (NMR)\ntechniques. We primarily concern on the intermediate cases: partial fringe\nvisibility and incomplete WW information. We propose a quantitative measure of\n$D$ by an alternative geometric strategy and investigate the relation between\n$D$ and entanglement. By measuring $D$ and $V$ independently, it turns out that\nthe duality relation $D^{2}+V^{2}=1$ holds for pure quantum states of the\nmarkers.",
