QUROPE Quantum Information Processing and Communication in Europe

Location

In Bristol we focus on optical realisations of quantum information primitives (CNOT gates, cluster states, quantum relays) using pairs and multipairs of photons generated using fibre optic pair photon sources. These exploit nonlinearities and novel phasematching in micro-structured optical fibres. These sources have demonstrated the highest efficiency for the production and detection of pair photons in well defined spatial modes and temporal modes. We are thus now linking these pair photons up to develop multiphoton sources which will allow multi-qubit information processing demonstrations. This project will investigate the development of ‘cluster state’ computation using these sources and metrology experiments exploiting the dual wavelength nature of the photons. The project will involve collaboration with the University of Bath and has strong links with EU projects.
