Recently I'm curious about the topic of open quantum system which is not talked about in common quantum mechanics textbooks, i.e. Master equation, Lindblad equation, reduced density matrix, entanglement entropy, correlation, decoherence, Gleason's theorem, Stinespring's theorem, Completely Positive and so on.
Are there some good references (easy and readable or rigorous and thorough) including papers, literatures or textbooks which can elucidate these topics related to open quantum systems?
