Abstract
We propose an experimental scheme utilizing the different travelling speed of photons at different frequencies to ‘erase’ the time sequential distinguishability of photons emitted from the two steps of an atomic cascade. Interference in joint detection requires not only the overlapping of the same photon in time through different paths, but also the presence of both photons simultaneously.Keywords
