Objective
The proposed project has the goal to combine the benefits of two of the most successful approaches to the processing of quantum information, individually trapped ions and strong-coupling cavity QED. While ions in a radio-frequency trap are an ideal stationary system to manipulate quantum states, photons have been demonstrated to faithfully transmit quantum states over larger distances. Intertwining the two fields is a precondition for distributed quantum computation, a scheme in which a calculation is spread over several local sites.
The principal challenge in the implementation of this scheme is the requirement for miniature-size traps and microscopic cavities, because only in this way suitable conditions for a strongly coupled interface between ions and photons are provided. The project will be realized by uniting researchers from the leading groups in the separate fields, which presently are spread over the European Union, to join their expertise to develop the required technologies and demonstrate their practical application. In the first phase of the project, novel methods for shrinking the mode volume of optical resonators will be investigated, including optical fibre cavities and small radius of curvature mirrors with ultra-low loss coatings.
In parallel, part of the team will construct a trap with a novel architecture, based on micro- or nano-fabrication techniques. Once a suitable apparatus is constructed, a large range of applications in quantum information processing is feasible. The team will use the set-up as a very efficient single-photon source and, reversing the dynamics, as an equally efficient single-photon detector. The ability to transfer quantum states in a photonic channel can be employed to create entanglement between ions and photons, two local ions or between ions in distant locations. This achievement would clearly demonstrate quantum networking and be the first implementation of the quantum Internet.
