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.

大多数电子设备都由传统晶体管提供动力，这些晶体管使用了50年历史的技术，该技术即将结束。基于自旋的电子设备使用电子旋转而不是电荷来存储，处理和传输信息。尽管芯片使用孔中的所有晶体管中有一半，但几乎所有研究都集中在电子上。孔具有与电子完全不同的自旋特性，并且预计基于自旋的量子信息处理具有显着优势。该项目旨在开发单孔量子点，测试孔优于电子优势的理论预测，并为全电动自旋操作开发新技术。
