摘要：

Let the density matrix of an arbitrary state be expressed in terms of number states as <(rho)over cap> = Sigma(n=0)(infinity)Sigma(m=0)(infinity)rho(n,m)\n][m\. We prove the following theorem: If rho(0,0)=O, then the state is as nonclassical as possible according to the measure introduced by Lee [Phys. Rev. A 44, R2775 (1991)].
