Quantum erasure by transverse indistinguishability

[摘要] 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. (C) 2000 Elsevier Science B.V. All rights reserved.
