It is clear from some more advanced variations on the double slit experiment (quantum erasure, etc) that retaining or destroying "information" on one half of an entangled pair affects the result of the other. The results tend to either be wave or particle type behavior on a detection device. I am wondering if it is the measurement method itself (by which we obtain this information) that causes the collapse of the pair? Or is it the actual information persistence about the pair? What I mean is can an experiment be created to demonstrate that I store information and one behavior happens, but if I destroy the information (say, the data on a hard drive from a monitoring device) so that it is no longer knowable, will the resulting behavior change?
