Instead of brute-force miniaturisation of basic electronic components, quantum computation utilises entirely new design architecture and promises to solve problems that are intractable on conventional computers.  It offers the prospect of harnessing nature at a much deeper level than ever before, as well as a wealth of new possibilities for communication and data processing. 

Core activities

The quantum dynamics and computation group conducts research in the areas of quantum dynamics, quantum information processing, and quantum computation. In addition to using advanced mathematical methods and numerical techniques to model the dynamics of quantum systems and to investigate quantum algorithms, the group also has extensive HPC and computer algebra expertise to solve a wide range of science and engineering problems.
