About the Project

The ICTM-group was established in 2012 at the University of Sussex by Matthias Keller with the intention to investigate and employ the interaction of ions and light and ions with atoms and molecules. Read more about our group here.

This project unites two distinct areas of quantum information processing: single ions stored in radio-frequency traps and single photons in optical fibres. Both fields have seen spectacular advances in recent years. Strings of ions are presently the most successful implementation of quantum computing, with elementary quantum algorithms and quantum simulations realised. Photons, on the other hand are used to distribute entanglement over ever increasing distances.

The principal challenge in the field is to enhance quantum processing power by scaling up current devices to larger quantum systems. We are pursuing one of the most promising strategies, distributed quantum computation, in which multiple small-scale ion processors are interlinked by exchanging photonic quantum bits via optical fibres. This requires novel ion trap structures that facilitate high-performance quantum computation and a photonic interconnect for networking. The Ion Trap Cavity-QED and Molecular Physics group in Sussex has a leading role in this field.
