Quantum Erasure by Transverse Indistinguishability
P. H. Souto Ribeiro, S. Padua, C. H. Monken
Abstract
We show that the first experiment with double-slits and twin photons detected in coincidence can be understood as a quantum eraser. The ``which path'' information is erased by transverse indistinguishability obtained by means of mode filtering in the twin conjugated beam. A delayed choice quantum eraser based on the same scheme is proposed.
