Abstract
We analyze the properties of nonclassical number states, specifically squeezed number states D(alpha)S(z)\n], and find their maximum signal- to-quantum noise ratio. It is shown that the optimal signal-to-quantum noise ratio for these states decreases as 1/(2n + 1)(2), where n is t he photon number, from the optimal value as derived by Yuen [Phys, Let t.
