Abstract

Optical systems are thoroughly investigated as platforms for the realization of information science tasks. The group led by Prof. Michal Lipson has pioneered nanophotonics on silicon chips, demonstrating ultrafast modulation, light confinement in very small volumes, and nonlinear optics on-chip. Our group, on the other hand, has been investigating quantum optics effects for the generation of entangled light beams, an important resource for applications in quantum information. The purpose of the present proposal is to investigate quantum properties of light on the silicon chips, uniting competences developed in both research groups. This shall enable the use of very efficient classical information systems in quantum information protocols. (AU)
