Implementing and manipulating telecom-wavelength-compatible quantum storage

We develop telecom wavelength compatible solid-state quantum bit systems and study their properties needed for quantum information storage. Based on our recent experiments, the exciton triplet states of carbon nanotubes seem to be a promising platform. The transmission range of optical fibres used to transfer photons to large distance is in the infrared range of 1350-1550 nm, whereas the solid-state realizations of quantum bits can be manipulated by visible light in the range of 500-700 nm. Bridging over this large wavelength difference on preserving the quantum information is a hard, so far unsolved problem. Our objective is to realize the direct quantum information transfer between nitrogen vacancy centres in diamond and carbon nanotubes via the Förster-type resonant exciton transfer process.
