Exact mapping of quantum waves between Unruh's and Afshar's setup (reply to W. Unruh).

In a recent letter, Unruh argued that I have misrepresented his position and I have "put words into his mouth" which distort Unruh's original analysis of Unruh's setup. Unfortunately such a complaint is ungrounded. I have presented a mathematical argument that Unruh's which way claim for the discussed setup is equivalent to the claim for a mixed density matrix of the experiment.

This is a mathematical proof, and has nothing to do with misrepresentation. Unruh clearly accepts the existence of the interference pattern at paths 5 and 6, accepts that the setup is described by ...
