Course objectives

The most peculiar characteristics of quantum mechanics are the existence of indivisible quanta and entangled systems. Both of these are the roots of Quantum Communication which could very well be the first engineered application of quantum physics at the individual quantum level.

The course aims at providing the fundamentals of quantum communication. Main applications with experimental implementations are presented. Experimental results and technological challenges are discussed.

Results of learning outcomes

Knowledge and understanding

-fundamental concepts of quantum information
-fundamental concepts of Quantum key Distribution with single photons
-fundamental concepts of entanglement-assisted quantum communication

Applying knowledge and understanding

- ability to critically assess the applicability of different approaches to quantum communication
