Quantum Quantum Textbook For Density Matrix, Pure & Mixed States, +more

[Login]

A Quantum Mechanics course I am taking is dumping a lot of material on us in a very short time. It's difficult to talk to the professor, and the only assigned class notes are PowerPoint slides which are not clear. So I am looking for a textbook that I can use to teach myself the material.

In our last lecture we were introduced to the following concepts, I would like a text that covers these as well:

• Relation between angular momentum algebra and the algebra of independent oscillators
• Something about how the ladder operators for the harmonic oscillator relates to creation and annihilation operators for bosons (not sure what the latter means)
• Number states
• Coherent states
• Squeeze states
• Squeezed coherent states
• Pure and mixed states
• Entanglement
• Reduced density operator + density operator
• Quantum teleportation

For the quantum mechanics work we had previously done, we were mostly working from Griffiths, so that is the level of understanding I am coming from.

Try looking at books in quantum optics and information.
