A characterization of the classical states of the quantum harmonic oscillator by means of de Finetti's theorem
Integral representations of statistical operators in terms of coherent states are derived by means of a quantum version of the Poisson limit of de Finetti's theorem [see \textit{R. L. Hudson} and \textit{G. R. Moody}, Z. Wahrscheinlichkeitstheor. Verw. Geb. 33, 343-351 (1976; Zbl 0304.60001)].
