Most electronic devices are powered by conventional transistors that use a 50 year old technology which is nearing the end of its lifetime. Spin-based electronics uses the electron's spin instead of its charge to store, process and transfer information. Although half of all transistors on a chip use holes, almost all research has focussed on electrons. Holes have completely different spin properties than electrons and are predicted to have significant advantages for spin based quantum information processing. This project aims to develop single hole quantum dots, test theoretical predictions of the superiority of holes over electrons and develop new techniques for all-electrical spin manipulation.

大多数电子设备都是由传统晶体管供电的，这些晶体管使用了50年前的技术，但其寿命已接近尾声。基于自旋的电子学利用电子的自旋而不是电荷来存储、处理和传输信息。尽管芯片上一半的晶体管都使用空穴，但几乎所有的研究都集中在电子上。空穴具有与电子完全不同的自旋性质，并且被预测在基于自旋的量子信息处理中具有显著的优势。该项目旨在开发单孔量子点，测试空穴优于电子的理论预测，并开发全电自旋操纵的新技术。
