Robust atomic quantum information processing networks in periodic lattice structures


The main scientific objective of this project is the development of schemes for scalable and robust quantum computing in periodic lattice structures which are feasible with current or short-term experimental technology. We plan to achieve this by using dec oherence free subspaces in ensembles of atoms stored in periodic traps and examine methods for performing robust single and two qubit gates in these subspaces. We will study implementations based on strong atomic interactions (e.g. controllable molecular i nteractions) and on flexible interactions mediated by a cavity field. These schemes are extended to quantum networks and we will check their suitability for implementation in concrete experimental setups. Such proposals have become realistic due to recent experimental breakthroughs in manipulating and controlling atoms in optical lattices and the networks we will investigate should allow to build special purpose quantum computers which can be used e.g. for small specific tasks in quantum cryptography or for simulations of more complicated quantum systems. The work on this project will boost my career and allow me to pursue my aim of becoming an independent researcher in the field of quantum information processing. I will be able to establish a number of new collaborations with groups in Oxford where an interdisciplinary research collaboration will link me furthermore to most of the current quantum information research inside the UK. In addition, the existing collaboration between the University of Oxford and the University of Innsbruck which both have centres for quantum computing would be strengthened and I would benefit from links to both centres in the future. A successful completion of the project will have significant impact on the field and thus contribu tes to enhance excellence and reputation of European research.
