QM books in order from easy to intermediate to hard

[Waxterzz]

So far I got:

Griffiths => easy, ok it's not so easy,not really what I ment, but it covers the basics without going much into the real deeper algebraïc stuff, emphasis on calculus, that's what I mean with easy, I mean a decent, solid book for undergraduate level.

But suppose I tackle Griffiths and I want a deeper understanding after that, what book should I read then.

Shankar? Sakurai? That book from Dirac? Cohen-Tannoudji Vol 1?

If I complete at least one of these, and I want to take a grasp on beginning Relativistic QM or maybe QFT. Or a different direction and Quantum Entanglement /Quantum Information or Path Integral formulation, what should I do then?

Oh, and most beginning books, they say: let's take an Hamiltonian that is not time-dependent, what if the Hamiltion is time dependent, what books should I read then?

One book that I like which is more advanced than Griffiths, but not at the level of Sakurai, is J. S. Townsend http://www.palgrave.com/page/detail/A-Modern-Approach-to-Quantum-Mechanics/?sf1=barcode&st1=9781891389788 . What I like about it is that it is indeed a "modern approach," and a good stepping stone towards quantum information. It also has things that are missing from Sakurai, like the density matrix and path integrals. I also like Cohen-Tannoudji.

Maybe unlike most others, I don't like this book very much and found it difficult to read and learn from. It shuns formalism, often to the detriment of clarity. The author tries too hard to achieve a casual style and sometimes behaves like a painfully uncomical comedian.

I also like Cohen-Tannoudji.

I second this. From what I remember from the time I still studied physics, I found this set unusually (unphysically? ) clear and pleasant to read, although I only consulted parts of it to complement a second course in quantum mechanics. It also seems very comprehensive. Based on my limited experience, I would recommend it.

When any of the textbooks treat time dependence, they usually use their sections on Time dependent- Perturbation Theory.

I think I like Shankar, but when I studied QM in grad school, they used Sakurai. I felt Cohen -Tannoudji too encyclopedic, about 2000 total pages in both volumes.(?)
