Abstract

The momentum changes caused by localization are a central feature of wave-particle duality. Investigating these changes in more detail, we find that single-slit diffraction relies on a form of 'interaction-free' scattering, and that an ideal which-way measurement can be made without any back-reaction on the detector. We also consider Kim and Shih's recent realization of Popper's experiment, involving diffraction of entangled particles, and offer an explanation for the results.
