    "abstract": "We present a conditional quantum eraser which erases the a priori knowledge\nor the predictability of the path a photon takes in a Young-type double-slit\nexperiment with two fluorescent four-level atoms. This erasure violates a\nrecently derived erasure relation which must be satisfied for a conventional,\nunconditional quantum eraser that aims to find an optimal sorting of the system\ninto subensembles with particularly large fringe visibilities. The conditional\nquantum eraser employs an interaction-free, partial which-way measurement which\nnot only sorts the system into optimal subsystems with large visibility but\nalso selects the appropriate subsystem with the maximum possible visibility. We\nexplain how the erasure relation can be violated under these circumstances.",
