What I understand of Fock states so far: They describe the quantum state of a bunch of photons. A single photon can be in several different energy states, and when these photons are tensored together - the basis for this is the Fock states.
A given Fock state has a certain intensity for various frequencies of light.
However light has several other properties - for example, the polarisation states which is described by a two dimensional Hilbert space for each photon, and the spatial degree of freedom, which, say for in a beam splitter set up, can also be described by a two dimensional Hilbert space. And there may be several other properties like angular momentum, etc.
How is the polarisation state of a photon related to it's energy state or related to states in the Fock basis?
Or are they separate things - Light in any Fock state (or a superposition of Fock states) can have any polarization?
If anyone can shed light on the other properties, that would be great as well.
I come from a quantum information background, and know very little optics and electromagnetism, so if anyone could explain it from that point of view, it would be great.
