Holographic quantum eraser experiment reveals polarization structure of depolarized light
Gerhard K. Ackermann, Jürgen Eichler · Applied Optics · 2008
It is shown that a holographic setup for real-time interferometry can be used to realize a quantum eraser (QE) experiment. Circular polarized light is used to distinguish between the photons of the reconstructed image of the object and the direct object wave consisting of scattered photons from the illuminated flat object. To erase the "which path information," a linear polarizer is used. The experimental results show that polarized light, after depolarizing reflection from a dielectric surface, contains an internal polarization structure, which can be described extending the well-known Jones vector formalism.
