# Delayed "Choice" quantum eraser

@article{Kim2000DelayedQ, title={Delayed "Choice" quantum eraser}, author={Kim and Yu. and Kulik and Shih and Scully}, journal={Physical review letters}, year={2000}, volume={84 1}, pages={ 1-5 } }

We report a delayed "choice" quantum eraser experiment of the type proposed by Scully and Druhl (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.
