Non-Abelian photon

In this paper, we have proposed $SU(2)$ non-Abelian electromagnetism gauge theory. In the theory, photon has self-interaction and interaction, which can explain photon entanglement phenomenon in quantum information. Otherwise, we find there are three kinds photons ${\gamma }^{+}$, ${\gamma }^{-}$ and ${\gamma }^0$, and they have electric charge $+e_{\gamma }$, $-e_{\gamma }$ and $0$, respectively, which are accordance with some experiment results.
