论文摘要
量子自旋霍尔边缘预计将可靠地在边缘的磁绝缘体和超导体型型区域之间的边界上产生Majorana零模式。磁化方向决定了诱导的磁间隙的大小，并可以控制所得的隧道屏障。在这里，我们提出了一种避免对材料进行磁性操作并使用屏障的局部控制的方法。我们按照量子自旋效果的量子效果的设计以及量子计算机的布局设计。我们估计相关量表，并表明它们允许在不久的将来测试这些想法。
The quantum spin Hall edge is predicted to reliably produce Majorana zero modes on the border between magnetic insulator- and superconductor-proximitized regions of the edge. The direction of magnetization determines the size of the induced magnetic gap and can control the resulting tunnel barrier. Here we propose a way to avoid magnetic manipulations of the material and use electric-only local control of the barrier. We follow with a design of a charging-energy-protected qubit and a layout of a quantum computer based on the quantum spin Hall effect. We estimate relevant scales and show that they allow for testing of these ideas in the near future.
