Since the electromagnetic field is already second quantized, this corresponds to a third quantization. This approach allows certain calculations in quantum optics to be performed in a straightforward way in the Heisenberg picture. Aside from being a useful computational tool, this approach allows an interesting generalization of quantum optics and quantum electrodynamics that could be tested experimentally.11 pagesen-USMay be used only for educational or research purposes.UMBC Quantum Information GroupText
