Personal Data

I’m associate professor at the department of computer science of the university of Århus, Denmark. I studied computer science at the university of Montreal where I got my Ph.D. in 1998 under the supervision of Gilles Brassard and Claude Crépeau. My main research interest is quantum cryptography.

In 1998, I came to the department of computer science at the university of Århus to work primarily on the development of a prototype for quantum key distribution. A center, called CKI, was established to support the experiment developed by a joint effort between the department of physics and computer science at the university of Århus. The goal was to provide a quantum key distribution system that fully implements all functionalities required for private message transmissions. This includes, on top of physical devices, all softwares necessary for efficient and provably secure transmissions.

I teach a course on quantum information theory on a yearly basis jointly with Ivan Damgård since 1998. The course’s webpage gives a detailed description for the previous semester (Fall 2006) content.

I teach an introductory course on relational databases. The course’s webpage gives a detailed description of all the topics we look at during this semester (Fall 2007).

I’m involved in the European project SECOQC as a research leader for the SECurity subproject. The project aims at implementing a global network for secure communication based on quantum key distribution. The project should culminate with a working quantum network implemented in Vienna and connecting a few sites using existing telecommunication fibers. SECOQC is the largest project on quantum cryptography having taken place in Europe. The project will end in 2007.

I’m also involved in a project called QUSEP funded by the Danish Agency for Science, Technology and Innovation. QUSEP aims at demonstrating the possibility of using quantum cryptography in practical 2-party settings with security proven in the bounded quantum-storage model. We are currently implementing an identification protocol over short optical fiber (less than 1 meter) optimized to run very efficiently.
