WASPS — ICT (2013-2016)

Single photon sources are an important element of the toolbox for new quantum technologies such as quantum cryptography and quantum computing. Although several different designs of single photon sources have been developed in the past, it remains difficult to make devices with appropriate specifications that can be used outside of laboratory environments.

This project seeks to develop a range of single photon sources that are easy to use and compatible with non-laboratory environments. The photons will be produced by defects in diamond, as the unique properties of this amazing material provide an excellent platform for single photon emitters that will be stable and long-lasting, ideal for devices that are both robust and reliable. In addition we introduce novel ways to control the photon emission process using ’optical microcavities’.

The WASPS project brings together six European research groups that are world leading in the science of diamond, optical microcavities, and quantum technologies, with theoretical physicists who have developed the ideas to exploit dephasing effects for controlling the light-matter interaction. The role of NEEL is first to provide theoretical support for the experiments conducted in the consortium, second to investigate the potential of phonon and carrier induced decoherence for quantum information purposes.
