Abstract

We aim at the generation of intense entangled light beams, with quantum correlations that are strong enough for successful implementation of teleportation in the continuous variables domain. Contrary to already existing systems, that rely on interferometry for entanglement generation, manipulation and measurement, we will use intense beams and self-homodyning techniques. They are necessary for the transfer of quantum information between different colors in the electromagnetic spectra. This will be the only setup with the ability to convey quantum information among systems operating at different wavelengths, allowing the building of hybrid architectures in quantum information and successful teleportation over longer distances.
