Title: Localization properties and high-fidelity state transfer in electronic hopping models with correlated disorder,
Abstract: We investigate a tight-binding electronic chain featuring diagonal and
off-diagonal disorder, these being modelled through the long-range-correlated
fractional Brownian motion. Particularly, by employing exact diagonalization
methods, we evaluate how the eigenstate spectrum of the system and its related
single-particle dynamics respond to both competing sources of disorder.
Moreover, we report the possibility of carrying out efficient end-to-end
quantum-state transfer protocols even in the presence of such generalized
disorder due to the appearance of extended states around the middle of the band
in the limit of strong correlations.
