Abstract
AbstractCanonical quantization has conventionally been adopted as a necessary procedure for the description of the quantum radiation field by analogy between quantum-mechanical oscillators and field oscillators. In this paper we provide the physical basis for the formal quantization of the radiation field interacting with matter in the presence of the vacuum field, taken here as a solution of classical Maxwell equations. Just as the canonical particle operators $$\hat{x}$$

have been shown to be the response functions of the particle to this field, here we derive the creation and annihilation operators $$\hat{a}^{\dagger }$$
