Quantum Security

I will focus my talk on quantum key distribution (QKD) - the most reliable way how to securely distribute cryptographic keys. The QKD is one of several applications of an emergent field of quantum (information) technologies. In order to appreciate better the transformative potential of quantum technologies I will explain basic principles of quantum physics. In particular, I will describe in detail two phenomena: quantum superpositions and a quantum entanglement. After this  a  detaled description of a quantum-key-distribution link between Vienna and Bratislava that has been opened in 2020 will follow. I will conclude my talk by a short presentation of the national plan for building a quantum communication infrastructure.
