Cramér–Rao Lower Bound for Magnetic Field Localization around Elementary Structures

Sensors
The determination of a mobile terminal’s position with high accuracy and ubiquitous coverage is still challenging. Global satellite navigation systems (GNSSs) provide sufficient accuracy in areas with a clear view to the sky. For GNSS-denied environments

Optimal sensing on an asymmetric exceptional surface

Physical Review Research
We study the connection between exceptional points (EPs) and optimal parameter estimation, in a simple system consisting of two counterpropagating traveling wave modes in a microring resonator.

Saturating the one-axis twisting quantum Cramér-Rao bound with a total spin readout

Journal of Physics Communications
We show that the lowest quantum Cramér-Rao bound achievable in interferometry with a one-axis twisted spin coherent state is saturated by the asymptotic method of moments error of a protocol that uses one call to the one-axis twisting, one call to time ...

Cramer-Rao Bounds for Misspecified Models

, 1986
In this paper, we derive some lower bounds of the Cramer-Rao type for the covariance matrix of any unbiased estimator of the pseudo-true parameters in a parametric model that may be misspecified. We obtain some lower bounds when the true distribution belongs either to a parametric model that may differ from the specified parametric model or to the ...
