Chris Perrella summarises paper “High-efficiency cross-phase modulation in a gas-filled waveguide”
We have produced a device that allows photons to interact with each other, based on the technology of gas-filled hollow-core optical fibre. Photon-photon interactions are difficult to engineer, but are crucial in applications such as quantum-optic logic gates and photon detectors; devices that are required for optical quantum computing.
