Silicon nanopillars for quantum communication

Around the world, specialists are working on implementing quantum information technologies. One important path involves light: Looking ahead, single light packages, also known as light quanta or photons, could transmit data that is both coded and effectively tap proof. To this end, new photon sources are required that emit single light quanta in a controlled fashion--and on demand. Only recently has it been discovered that silicon can host sources of single-photons with properties suitable for q...
