    "abstract": "The notion of wave-particle duality may be quantified by the inequality\nV^2+K^2 \u003c=1, relating interference fringe visibility V and path knowledge K.\nWith a single-photon interferometer in which polarization is used to label the\npaths, we have investigated the relation for various situations, including\npure, mixed, and partially-mixed input states. A quantum eraser scheme has been\nrealized that recovers interference fringes even when no which-way information\nis available to erase.",
