Quantum squeezing amplification with a weak Kerr nonlinear oscillator
Fig. 4, panel (b)
Allan deviation $\sigma_\alpha$ of the displacement estimate against the number of independent measurements $N_{\mathrm{meas}}$, for squeezed states made with $M = 1$ (red) and $M = 13$ (green) Trotter steps: measured (circles, standard deviations of repeated experiments as error bars), with the Cramer-Rao bounds from the classical (dashed) and quantum (solid) Fisher information.
