State Transfer Analysis for Linear Spin Chains with Non‐Uniform On‐Site Energies

Year: 2025

Type: article

Abstract: ABSTRACT High fidelity state transfer is an important ingredient of distributed quantum information processing. We present and analyse results on perfect and quasi‐perfect state transfer with linear spin chains incorporating non‐uniform on‐site energies. The motivation is maintenance of coupling uniformity, which could be beneficial for some physical implementations. We relate this coupling uniformity to a particle in a discrete potential analogue. Our analysis further considers the statistical variation in couplings and on‐site energies, as a function of increasing chain site number .
