Quantum memories for scalable photonics - Joshua Nunn

Technologies that harness the quantum properties of light could enable secure communications, improved sensing and faster computing. But photon sources, photon-photon logic gates, and photon detectors are all probabilistic, so only small-scale experiments have so far been possible. Scaling up to larger devices requires synchronising each component, which can be done with quantum memories. I will show how even inefficient memories can dramatically increase the success rate of generating photons, and I will describe experimental progress in Oxford towards implementing a quantum memory for photons in cesium vapour.
