我们讨论了一个由Kitaev导线组成的网络，该网络耦合到几个单独可调的量子点，作为最近在量子点上耦合到具有Majorana零模的纳米线上实验的扩展[邓等人。科学354 1557(2016)和邓等人。Arxiv：1712.03536(2017年)]。该装置的特点是具有精确零能量的局域Majorana模，并且我们证明了它们可以通过单独作用于量子点来操纵。通过将三根导线布置为一个三结点，可以得到编织过程，并且量子点的电荷读出可以用来揭示Majorana零模的非阿贝尔统计。该装置可以扩大规模，以服务于更高级的拓扑量子计算目的。
We discuss a network of Kitaev wires coupled to several individually-tunable quantum dots as an extension of the recent experiments on a quantum dot coupled to a nanowire hosting Majorana zero modes [Deng et al. Science 354 1557 (2016) and Deng et al. arXiv:1712.03536 (2017)]. The setup features localized Majorana modes with exact zero energy and we show that they can be manipulated by solely acting on the quantum dots. A braiding process can be obtained by arranging three wires as a trijunction and a charge readout of the quantum dots can be used to reveal the non-Abelian statistics of Majorana zero modes. The setup can be scaled up to serve the more advanced purposes of topological quantum computation.
