Summary on Grant Application Form |

In recent years quantum information research has lead to the discovery of a number of remarkable new paradigms for information processing and communication. These developments include, for example, quantum cryptography schemes that offer unconditionally secure information transport guaranteed by quantum mechanical laws and quantum computers that, if realised, would make todays public key based data security systems obsolete. Evidently these new, and potentially disruptive, security technologies could be of high strategic and economic value in the future. An important challenge for the research community, therefore, is to develop practical quantum communication and processing systems in order to achieve credibility for these advanced new concepts. This project aims to contribute towards this goal by designing, building and testing a high speed quantum cryptography system that operates at GHz clock rates ie some 3 orders of magnitude higher than the current state of art. The project will also demonstrate feasibility and examine the issues involved in the use of quantum key distribution in multi user optical fibre networks.
