In the present day there is only one commercial application of quantum information processing (QIP), quantum key distribution, and the market embracing it is small. The development of further applications requires the realisation of a suite of practical devices that are able to create, buffer, process and repeat quantum information. Semiconductor structures have dominated digital information’s history, as their ease of use and scalability are both ideal in meeting market demands. In the Quantum Technology Centre at Lancaster University we are developing semiconductor devices for practical applications of QIP, and in this talk I will discuss our progress.
