I'm working on a project on quantum measurement theory - in particular, relating to the quantum Zeno effect - over the summer. Right now, I'm in the process of doing background readings that'd enable me to tackle the problem in a few weeks.
I'm looking for a resource recommendation for a QM textbook (for self-study, of course) that deals with the ideas of density operators, mixed states, entangled states, Bell's Inequality, CHSH and other topics that may fall in this category. Most of the undergraduate textbooks I have read thus far (mainly Shankar, Townsend and Beck) don't include these topics.
I'd appreciate if someone could recommend related textbooks on this front, ideally suited for a third year undergraduate who has done standard undergraduate QM sequence.
