This is a very clear and technical text, something I have been looking for some time (to teach from). However, this should not be read on its own because it does not explain why the algorithms work beyond that the algebra works. We need to think a bit more about the design decisions behind the algorithms. Nevertheless I am quite happy that the Shor's algorithm part includes probability analysis at the undergraduate level, something missing from a lot of other texts.
