Introduction to Quantum Networks
Miralem Mehic, University of Sarajevo
5-6pm 22nd Nov 2018
One of the central issues in cryptography is a secure distribution of key between geographically distant users, known as secret key agreement problem. The current solutions in most applications are based on the usage of public key infrastructure (PKI) which relies on assumptions about the computation power of eavesdropper and computational complexity of mathematical problems. As results, these solutions fall within the scope of theoretically breakable computational security and with the increase of computational power such solutions are under threat. Quantum information theory suggests the possibility of solving the secret key agreement problem by using an information-secure quantum key distribution, known as QKD. Based on the laws of physics, QKD provides a secure way of establishing symmetrical binary keys between two geographically distant users without relying on the hardness of mathematical problems. The presentation provides an introduction to quantum networks including BB84 protocol, quantum networks, quantum simulators and quality of service in quantum networks.
Dr Miralem Mehic (male) was born in 1988 in Bosnia and Herzegovina. He received B.S. and M.S. degrees in telecommunications from the University of Sarajevo, Bosnia and Herzegovina in 2007 and 2012 and the PhD degree in telecommunications from the VSB-Technical University of Ostrava, Czech Republic in 2017. Also, he studied at the AGH University of Science and Technology, Krakow, Poland, Alpen-Adria-Universitat Klagenfurt, Austria and Austrian Institute of Technology (AIT) in Department of Digital Safety & Security Business Units - Optical Quantum Technology, Vienna & Klagenfurt, Austria. Miralem is the author of the unique quantum network simulator QKDNETSIM, and he participated in the successful realization of the virtual Austria-Czechia QKD link. Some of his works have been published in leading journals ranked in Q1 and Q2 quarters (IEEE Access, Quantum Information Processing, IEEE Journal of Quantum Electronics) while his work on quantum network signaling protocols was awarded as the best paper at the MCSS 2017 conference in Krakow, Poland. His field of research is related to the quality of service and management of quantum networks with a focus on real-time traffic and the utilization of network resources. Miralem is an assistant professor with Dept. of Telecommunications, Faculty of Electrical Engineering, University of Sarajevo, Bosnia and Herzegovina.
