Palacky University Olomouc, Czech Republic, announces the opening of a 1+1-year position for a post-doctoral researcher in quantum communication theory with quantum dot sources within an EU-funded project in the quantum communication team led by Dr. Vladyslav Usenko within the quantum optics theory group of Prof. Radim Filip. The research will primarily focus on novel quantum key distribution protocols using entangled states with suppressed multi-photon contribution in quantum networks and include international experimental-theoretical collaboration.
