Curriculum Vitae
Publications
Dr. Rupert Ursin is a group leader and senior scientist at the IQOQI. His main field of research is to develop quantum communication and quantum information processing technologies, mainly for free-space, but also for fibre-based systems. The scope of his work ranges from near term engineering solutions for secure key sharing (quantum cryptography) to more speculative research (de-coherence of entangled states in gravitational fields). Experiments on quantum communication and teleportation using entangled photon pairs is also among his interests, with the long- term goal of a future global quantum network based on quantum repeaters. He has been experimentally active in numerous international collaborations in Germany, Italy, Spain, USA as well as in China and Japan. Lead several ESA funded projects as well as on the national and EU level. These allowed him to perform highly recognized experimental studies e.g. on a 144 km free-space link between La Palma and Tenerife [1] (cited more than 450 times). His group is performing time-energy entanglement distribution over a turbulent atmosphere just recently [5]. To date he and his publication recived several international awards and prizes. He was invited to several prestigious conferences to deliver talks (e.g. IEEE, SPIE, QCMC and others) and serves to important conferences as a program committee member e.g. ICSOS, SPIE, QCrypt and others. He currently holds a guest professorship at the University of Science and Technology (USTC) in Shanghai, China.
Research interests
Research interests include fundamental physics experiments on topics related to quantum optics and quantum information and their applications. Focus on the development of technologies required to perform space-based experiments concerning quantum information technologies. Numerous project partners in various fields (academic as well as industrial) together with national space agencies and the European Space Agency (ESA) are involved in this project. Contacts to international collaborators in Japan, China and USA are important partners to perform quantum communication on a global scale.
