Abstract
We report a delayed “choice” quantum eraser experiment of the type proposed by Scully and Drühl (where the “choice” is made randomly by a photon at a beam splitter). The experimental results demonstrate the possibility of delayed determination of particlelike or wavelike behavior via quantum entanglement. The which-path or both-path information of a quantum can be marked or erased by its entangled twin even after the registration of the quantum.Keywords
