In the delayed choice quantum eraser (DCQE), such as the walborn paper, link below:
http://arxiv.org/PS_cache/quant-ph/pdf/0106/0106078v1.pdf"
we try to find out the polarization/path via quarter wave plates (see diagram on page 7 of the paper)
Now does not entanglement break (i.e. wave function collapse) at that point?
later when we erase which-way info, does the same entanglement again re-join?
what is the popular explanation among physicist on this?
