Robust Phase Estimation of Squeezed State (1301.7144v1)
Published 30 Jan 2013 in quant-ph, cs.SY, and math.OC
Abstract: Optimal phase estimation of a phase-squeezed quantum state of light has been recently shown to beat the coherent-state limit. Here, the estimation is made robust to uncertainties in underlying parameters using a robust fixed-interval smoother.
