starts with light polarization, then moves on to spin, and doesn't arrive at the Schrödinger equation until chapter 9. This is the only undergrad quantum mechanics book of which I know that gives a detailed treatment of why photons are not needed to explain the photoelectric effect (probably some undergrad quantum optic texts also do this)..
It starts with single-photon interferometers and spin-1/2 particles as two-level systems in chapter 2, then talk about the formalism, entanglement, correlated states, maps and measurements (density operators, CP maps and POVMs). Not until the second half of the book do they introduce infinite dimensional systems.
