Marie Curie Initial Training Network -
Coherent Information Processing in Rare-Earth Ion Doped Solids

Rare-earth ions (lanthanides) play an increasingly important role in modern optical technologies. Lanthanides are extensively used in solid-state laser physics, e.g. as key components in telecommunication networks. Rare-earths are also employed as luminescent materials in lamps or as radiation detectors in X-ray imaging. Rare-earths are already commercially omnipresent.

However, the full potential of rare-earth ions is not yet explored – in particular with regard to the rapidly evolving field of future information technology. Future data storage and processing will require novel types of memories (e.g. based on interactions between light and quantized matter), algorithms (e.g. based on quantum computations) and materials (e.g. appropriate quantum systems). Rare-earth ion doped solids are very promising candidates to permit implementation of future quantum technology. The media combine the advantages of solids (i.e. large density and scalability) and atomic gases (i.e. long coherence times).

CIPRIS will build on the advantages of rare-earth doped media and drive applications towards future information technology. CIPRIS follows two scientific approaches : Classical processing and quantum processing. Both are meant as pronounced inter-disciplinary research efforts, combining physics, material science and information technology. To exploit the results, the public and private sector partners will closely cooperate to develop commercial demonstration devices.
In terms of training, CIPRIS aims at the development of the next generation of young researchers with appropriate skills in rare-earth-based information technology – pushing it towards commercial applications. CIPRIS offers a large variety of training actions, e.g. mini schools, laboratory courses, secondments to the private sector, or training sessions to strengthen complementary skills and contacts to the private sector. This will contribute to a European knowledge base for future information technology.
