Cavity-QED Tests of Representations of Canonical Commutation Relations Employed in Field Quantization

Various aspects of dissipative and nondissipative decoherence of Rabi oscillations are discussed in the context of field quantization in alternative representations of CCR. Theory is confronted with experiment, and a possibility of more conclusive tests is analyzed. KEY WORDS: quantization; cavity quantum electrodynamics; canonical commuta-tion relations; Rabi oscillation
