 Project objective

Single photon sources are essential for applications of quantum optics. For optical quantum computing the process is probabilistic and so the larger the number of photons the less time required for success. Therefore, there has been a push to increase the brightness of single photons sources. This goal of this action is to develop a source of heralded single photons with a very high spectral brightness, based on four-wave mixing in an alkali-vapour contained in a hollow core photonic crystal fibre. This will exploit the higher efficiency expected from using a hollow core fibre to boost the brightness of the single-photon source. Also, by using optical fibre technology, this photon source should be very simple to integrate into other systems. Once the photon pairs are generated, the major challenge of this system will be to split them from themselves, as well as removing the vast number of remaining pump photons. Since all three wavelengths of the light emerging from the fibre are very close to each other, and the beams are spatially overlapped, many common techniques (such as using interference filters and/or spatial filtering) will not work. However, we have identified a scheme using an atomic Faraday filter which will allow a beam splitter to be formed for the photon pairs, whilst simultaneously removing the pump photons.

Are you the coordinator (or a participant) of this project? Plaese send me more information about the "SPIRAL" project.

For instance: the website url (it has not provided by EU-opendata yet), the logo, a more detailed description of the project (in plain text as a rtf file or a word file), some pictures (as picture files, not embedded into any word file), twitter account, linkedin page, etc.

Send me an  email ( and I put them in your project's page as son as possible.

Thanks. And then put a link of this page into your project's website.

The information about "SPIRAL" are provided by the European Opendata Portal: CORDIS opendata.
