Optimal Signal-to-Quantum Noise Ratio for Nonclassical Number States
arXiv:quant-ph/9712020 · doi:10.1016/S0030-4018(98)00202-8
Abstract
We analyze the properties of nonclassical number states, specifically squeezed number states D(a)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 the photon number, from the optimal value as derived by Yuen.
