Oh What an Entangled Web We Weave...

I looked up "entanglement" in the indexes of half a dozen quantum mechanics texts I have around here. Didn't find it. The spooky quantum entanglement that so bothered Einstein doesn't feature heavily enough in any of them to make the index. Quantum Mechanics: The Theoretical Minimum isn't like that. Leonard Susskind and Art Friedman put quantum entanglement at the center of their book. For them, entanglement is the most novel and one of the most important features of quantum, as well as one that is consistently neglected in textbooks. I happened upon the book more or less by accident. I was wandering through a bookstore with one of my old graduate school office mates, arguing, as usual, about Bell's Theorem, realism in quantum mechanics, and so on. I suddenly realized that I really was a bit unclear on exactly what was meant by quantum entanglement. Since it was a bookstore and we were in the physics section, I looked around for a QM book and there w...
