Hi
I would like to know how you get from the classical 4-vector polarization
to the two component quantum polarization?

thank you

Mark

You might want to rephrase your question to include more detail,
since it's not very clear what you're really asking. I'm guessing
you're interested in something about the 2-component polarization
of photons and maybe neutrinos, but... hmm... I'm not sure from your
question.

yes I am interested in how one gets a 2-component polarization of a photon (which represents a quantum bit) from a 4-component classical polarization vector.

thanks

A classical EM wave also has only two independent possible polarizations.

(I.e., you're still not giving enough background/detail in your question to enable
a satisfactory answer.)
