Abstract
We write down a fully covariant formulation for the photon wavefunction
and show, in the simplest case of a single free photon, the
equivalence with QED formulation of the electromagnetic field in
vacuum. This result is extended to an N-photon wavefunction, and
quantum states such as entanglement and orbital angular momentum are
described as properties of a multi-photon equation.
