Dr Ruth Oulton and Professor John Rarity at the Centre for Quantum Photonics have been awarded a €2 million Future and Emerging Technologies grant from the European Commission and a €1.1 million CHIST-ERA award from European national funding agencies, including the EPSRC.

The use of particles of light, photons, to encode and send information could revolutionise the way we secure all internet transactions, while computing using photons promises much faster ways of tackling hard problems. The aim of both these projects is to use semiconductor devices to mediate the interaction between photons providing a quantum memory and quantum logic gates to extend these quantum applications to longer distances and harder problems.
