Hi.
In a Mach-Zehnder interferometer, there are mirrors in both paths. When a photon gets reflected on a mirror, it transfers momentum. Also, mirrors are classical objects that are usually not assumed to exist in superposition states.
Shouldn't it (at least in principle) be possible to measure the forces on the mirrors, which would reveal the path taken and therefore destroy the superposition and interference on the screen?
