Abstract

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.

• I am trying to understand one specific point about the Kim et al. delayed-choice quantum eraser . In the usual description, the total pattern at D0 shows no interference. But if the D0 events are late [stackexchange, 1 points]
