You might be interested in an article in the May issue of Scientific
American, "A Do-It-Yourself Quantum Eraser," May, 2007, pp.90-95. (03)
Supplemental material for the article can be found at:
http://www.sciam.com/article.cfm?articleID=E20B77CB-E7F2-99DF-33669D92032DFF8C (04)
From the article: (05)
"We will show you how to set up an experiment that illustrates what is
known as quantum erasure. This effect involves one of the oddest
features of quantum mechanics-the ability to take actions that change
our basis interpretation of what happened in past events." (06)
Hope you are having a great day! (07)
