Noise-Whitened Observability Geometry in Dynamical-Decoupling Spectroscopy

Introduces a covariance-dependent observability geometry for dynamical-decoupling spectroscopy using the noise-whitened Fisher metric F=JTΣ−1JF = J^T\Sigma^{-1}JF=JTΣ−1J. The work shows that correlated observational noise induces smooth but localized geometric reorganization, including substantial soft-mode rotation and anisotropy redistribution in reduced inverse-map geometry.

Abstract

Introduces a covariance-dependent observability geometry for dynamical-decoupling spectroscopy using the noise-whitened Fisher metric F=JTΣ−1JF = J^T\Sigma^{-1}JF=JTΣ−1J. The work shows that correlated observational noise induces smooth but localized geometric reorganization, including substantial soft-mode rotation and anisotropy redistribution in reduced inverse-map geometry.
