自旋输运和准二维施体量子计算体系结构

Spin transport and quasi 2D architectures for donor-based quantum computing

L. C. L. Hollenberg, A. D. Greentree, A. G. Fowler, C. J. Wellard

摘要:

通过引入一种新的电子自旋输运机制,提出了一种二维施主电子自旋量子计算机体系结构。该设计解决了原始凯恩设计中的主要技术问题,包括交换耦合强度的空间振荡和门控制中的串扰。还预期在量子位门中引入一定程度的非局部性将显著提高最近邻线性阵列的缩放容错阈值。

英文摘要:

Through the introduction of a new electron spin transport mechanism, a 2D donor electron spin quantum computer architecture is proposed. This design addresses major technical issues in the original Kane design, including spatial oscillations in the exchange coupling strength and cross-talk in gate control. It is also expected that the introduction of a degree of non-locality in qubit gates will significantly improve the scaling fault-tolerant threshold over the nearest-neighbour linear array.
