Programme Grant Support
We have recently (January 2012) received new five year funding from the EPSRC, entitled Semiconductor Integrated Quantum Optical Circuits, to develop the physics and technology to enable the realisation of Semiconductor Integrated Quantum Optical Circuits.
Prototype quantum optical circuit showing key components, based on GaAs-materials.
Overview of the Project
The Programme Grant funded by EPSRC targets the first Semiconductor Integrated Quantum Optical Circuits, shown schematically in the figure above. This goal aims to bring to fruition many of the key advances at the level of single component III-V nanostructures, opening up long term exploitation in diverse fields of quantum information science. Towards this global target we anticipate ground breaking achievements in semiconductor physics and solid-state quantum optics. Furthermore, major technology developments will be driven by our programme including deterministic positioning of quantum dots and integration of superconducting single photon detectors on semiconductor chips.
To achieve our aims we have assembled a specially-selected team of investigators from the University of Sheffield, and from the Universities of Cambridge, Heriot-Watt and Lancaster. The non-Sheffield teams are led by D A Ritchie, R H Hadfield and V Falko respectively. Together they provide a very wide spread of expertise to achieve our goals. Our expertise is further enhanced by our links with the National Centre for III-V Technologies at Sheffield, providing access to high-class crystal growth and device processing.
The investigators of the grant are:
- Sheffield: M S Skolnick (PI), A M Fox, P Kok, D N Krizhanovskii, A I Tartakovskii, D M Whittaker, L R Wilson.
- Cambridge: D A Ritchie
- Heriot Watt: R H Hadfield
- Lancaster: V I Falko.
There will be six postdoctoral researchers working on the grant in Sheffield, and one each in the other three institutions, and up to 12 PhD students whose research will be devoted to Programme grant topics.
