    "abstract": "We analyze the properties of nonclassical number states, specifically\nsqueezed number states D(a)S(z)|n \u003e, and find their maximum signal-to-quantum\nnoise ratio. It is shown that the optimal signal-to-quantum noise ratio for\nthese states decreases as 1/(2n+1)2, where n is the photon number, from the\noptimal value as derived by Yuen.",
