comment Why does the quantum eraser seem to violate energy and momentum conservation?
My problem concerns how the beam changes its spatial distribution, without energy. Obviously, to change the distribution (from non-interference to interference) so that the particles are detected in bands of constructive interference would require a push away from the destructive interference positions. There must be a driving force behind this change. However, in the quantum eraser it is claimed that only the "in principle knowability of distinguishing information" is accountable for this change in statistics. There is no "driving force". This is a violation of conservation.
