论文摘要
Majorana Fermions是量子计算中即将到来的技术的有前途的基础。然而，由于与其他拓扑琐碎的费米子状态伴随着竞争，它们的非歧义鉴定仍然是一个困难的问题，这些状态在大多数光谱探针中都毒害了它们的检测。通过采用数值和分析方法，我们在这里表明，Fano因子断层扫描是Majorana绑定状态的关键独特特征，显示出与一个相当于一个的空间恒定泊松值。相比之下，其他琐碎的费米态的狂热因子，例如Yu-Shiba-Rusinov或Andreev的Fermionic态，在空间上是很大程度上依赖的，并且超过了一个，这是局部粒子孔对称性破坏的直接结果。
Majorana fermions are promising building blocks of forthcoming technology in quantum computing. However, their non-ambiguous identification has remained a difficult issue because of the concomitant competition with other topologically trivial fermionic states, which poison their detection in most spectroscopic probes. By employing numerical and analytical methods, here we show that the Fano factor tomography is a key distinctive feature of a Majorana bound state, displaying a spatially constant Poissonian value equal to one. In contrast, the Fano factor of other trivial fermionic states, like the Yu-Shiba-Rusinov or Andreev ones, is strongly spatially dependent and exceeds one as a direct consequence of the local particle-hole symmetry breaking.
