Abstract
Intensity versus position data of interference patterns produced by a double slit apparatus were collected. The double slit had mutually orthogonal polarizing filters over each slit acting as quantum markers, and a third polarizing filter after the markers acting as a quantum eraser. The visibility of double slit interference was calculated to be (1.60±0.02)×10-1 without the markers or eraser, (4.06±0.06)×10-2 with the markers, and (1.38±0.02)×10-1 with the markers and eraser.
