Today, quantum science has gone so far that several concepts of quantum information networks have already been implemented in the world, such as DARPA QKD, SECOQC Vienna, Tokyo QKD, Geneva area network, QUESS China, and others. Quantum photonics, shortly, will undoubtedly move from scientific laboratories to innovative cryptographic communication technologies, because the speed of photon propagation is the speed of light and photon coding can be realized in different states of frequency, phase, amplitude, polarization, and time. Besides, existing fibre optic transmission systems can provide part of the technological infrastructure required for future quantum communications. Within the study course, students will gain knowledge about quantum information transmission, quantum keys, quantum communication protocols, and the possible engineering infrastructure of the future quantum Internet.
