论文摘要
磁分子在未来量子设备中作为单位的可用性研究了。鉴于量子计算，必要的先决条件是低洼水平叠加的长期连贯时间。在本文中，我们通过数值模拟调查单离子易向各向异性轴的环形结构是否是有利的。我们的结果表明，旋转磁分子没有一般优势，但是在许多情况下，倾斜各向异性轴的排列表现最好。
Magnetic molecules are investigated with respect to their usability as units in future quantum devices. In view of quantum computing, a necessary prerequisite is a long coherence time of superpositions of low-lying levels. In this article, we investigate by means of numerical simulations whether a toroidal structure of single-ion easy anisotropy axes is advantageous as often conjectured. Our results demonstrate that there is no general advantage of toroidal magnetic molecules, but that arrangements of tilted anisotropy axes perform best in many cases.
