Third quantization of the electromagnetic field

We consider an approach in which the usual wave function quadrature representation of mode j electromagnetic field is further quantized to produce a operator. Since already second quantized, this corresponds additional or third quantization. The third-quantization can be used perform certain quantum optics calculations Heisenberg picture that could only performed Schrodinger when using conventional second-quantized theory. This also allows interesting generalization and electrodynamics analogous symmetry breaking elementary particle predictions generalized theory tested proposed photon scattering experiment.
