Query: Incorporating the Stern-Gerlach delayed-choice quantum eraser into the
  undergraduate quantum mechanics curriculum   As "Stern-Gerlach first" becomes the new paradigm within the undergraduate
quantum mechanics curriculum, we show how one can extend the treatment found in
conventional textbooks to cover some of the exciting new developments within
the quantum field. Namely, we illustrate how one can employ Dirac notation and
conventional quantum rules to describe a delayed choice variant of the quantum
eraser which is realized within the Stern-Gerlach framework. Covering this
material, allows the instructor to reinforce notions of changes of basis
functions, quantum superpositions, quantum measurement, and the complementarity
principle as expressed in whether we know "which-way" information or not. It
also allows the instructor to dispel common misconceptions of when a
measurement occurs and when a system is in a superposition of states. We
comment at the end how a similar methodology can be employed when the more
conventional two-slit experiment is treated.
