dc.description.abstractWe report on a delayed-choice quantum eraser experimentbased on a two-photon imaging scheme using entangled photon pairs.After the detection of a photon which passed through adouble-slit, a random delayed choice is made to erase or not erasethe which-path information by the measurement of its distantentangled twin; the particle-like and wave-like behavior of thephoton are then recorded simultaneously and respectively by onlyone set of joint detection devices. The present eraser takesadvantage of two-photon imaging. The complete which-pathinformation of a photon is transferred to its distant entangledtwin through a “ghost" image. The choice is made on the Fouriertransform plane of the ghost image between reading “completeinformation" or “partial information" of the double-path.
