Query: Comment on "Relativity of Quantum States in Entanglement Swapping:
  Violation of Bell's Inequality with no Entanglement"   In a recent interesting article Chris Nagele, Ebubechukwu O. IloOkeke, Peter
P. Rohde, Jonathan P. Dowling, and Tim Byrnes discuss an entanglement swapping
experiment using a setup where it is possible to switch the time ordering of
measurements. I would like to draw your attention to the fact that the very
same idea was introduced in two previous papers, and briefly address some
important points related to the subject.
