    "abstract": "In an interferometer, path information and interference visibility are\nincompatible quantities. Complete determination of the path will exclude any\npossibility of interference, rendering the visibility zero. However, if the\ncomposite object and probe state is pure, it is, under certain conditions,\npossible to trade the path information for improved (conditioned) visibility.\nSuch a procedure is called quantum erasure. We have performed such experiments\nwith polarization entangled photon pairs. Using a partial polarizer we could\nvary the degree of entanglement between object and probe. We could also vary\nthe interferometer splitting ratio and thereby vary the a priori path\npredictability. We have tested quantum erasure under a number of different\nexperimental conditions and found good agreement between experiments and\ntheory.",
