标题： State transfer analysis for linear spin chains with non-uniform on-site energies

摘要： 高保真状态传输是分布式量子信息处理的重要组成部分。 我们提出并分析了关于线性自旋链中完美和准完美状态传输的结果，这些自旋链包含非均匀的本地能量。 动机在于保持耦合的均匀性，这可能对某些物理实现有益。 我们将这种耦合均匀性与离散势模拟中的粒子联系起来。 我们的分析进一步考虑了耦合和本地能量的统计变化，作为链站点数 N 增加的函数。 显示英文摘要

摘要： 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 N.
