Predicting electric-field noise in ion traps using fluctuation electrodynamics
This method uses fluctuation electrodynamics to predict electric-field noise from fluctuations in dielectrics and metals within ion traps. By linking noise to dissipation via the fluctuation-dissipation theorem, it allows for quantitative predictions of heating rates. The study shows that dielectric noise dominates under certain conditions and provides design guidelines for minimizing heating in trapped-ion systems.
