See any freshman physics book, or one more advanced, to learn that electromagnetic waves are transverse, and that does it --transverse => two polarization states. Very basic stuff.

can some one explain 2 me the basis of photon polarization ...?
Photons are "generated" when a charge moves in a specific way. If
the charge moves up and down, the photons that fly off will be polarized
linearly.
If the charge spins around, they will be polarized circularly and one of two
ways depending on which way it spins, CW or CCW.
It's called "helicity operator eigenvalues". Why the photon has two instead of 3, well, it's called "gauge invariance". "Photon polarization" is a bit of an oxymoron, as "polarization" is typical to wavelike phenomena, while "photon" is a particle.
I would like to know how to calculate the ##[\hat{H}, \hat{P}]## for a particle in a 1D box? At the first glance it seems that they commute but they don't get diagonalized in identical basis. How to calculate this commutation?
I don't know why the electrons in atoms are considered in the orbitals while they could be in sates which are superpositions of these orbitals? If electrons are in the superposition of these orbitals their energy expectation value is also constant, and the atom seems to be stable!
