Future advances in computer technology will exploit quantum physics to deliver increased computational power, either through new materials or quantum information approaches. However although half of the 100 billion transistors in your iphone use holes to operate, most semiconductor quantum research has focussed on electrons. Holes have completely different quantum spin properties than electrons; recent advances show holes have highly desirable properties for spin based quantum information. This project will work with leading European laboratories to develop quantum computer components based on hole spin in quantum dots in industrially relevant semiconductors, and demonstrate a pathway towards a scalable quantum computer architecture.

计算机技术的未来发展将利用量子物理学来提供更高的计算能力，无论是通过新材料还是量子信息方法。然而，尽管iPhone上的1000亿个晶体管中有一半是利用空穴来工作的，但大多数半导体量子研究都集中在电子上。空穴具有与电子完全不同的量子自旋性质;最近的进展表明，空穴对于基于自旋的量子信息具有非常理想的性质。该项目将与欧洲领先的实验室合作，开发基于工业相关半导体量子点中空穴自旋的量子计算机组件，并展示可扩展量子计算机架构的途径。
