 The study investigates the source of emotional heating in iron-trap quantum computers and finds that fluctuations of adsorbate dipoles are likely responsible. The research analyzes the behavior of both in-plane and out-of-plane vibrational modes of 21 adsorbate electrode combinations using first-principles computational methods to determine surface-induced dipole moments. The study finds that the chemical specificity of the adsorbate can change the electric field noise by seven orders of magnitude, with soft in-plane modes of weakly-absorbed hydrocarbons producing the greatest noise in iron heating. The research discusses the dynamics captured by the fluctuating dipole model and suggests future research directions for improved, quantitatively predictive models based on extensions of the present framework to multiple intacting adsorbates.
