Hole quantum dots - a new spin on quantum information technology

大多数电子设备是由传统晶体管供电的，这些晶体管使用的是一项已有50年历史的技术，而这项技术的寿命即将结束。基于自旋的电子学使用电子的自旋而不是它的电荷来存储、处理和传输信息。尽管芯片上一半的晶体管使用空穴，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，被预测在基于自旋的量子信息处理中具有显著的优势。该项目旨在开发单空穴量子点，测试空穴优于电子的理论预测，并开发全电子自旋操纵的新技术。

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.
