Quantum Communication - Tutorial for IT Specialists (Dr. Peter Holleczek) / german language

The history of the development of data communications has actually been told. Progress is currently limited to a slight increase in transmission rates. Progress is hampered technically by ever more arduous miniaturization and organizationally by ever more stringent security requirements. Leap innovations are again lacking.

One comes, albeit from physics, from quantum physics. Quanta, especially light quanta (photons) on the one hand make miniaturization / “atomization” appear from a new angle and on the other hand have properties that are of extreme value in the encryption of data.

The tutorial is addressed to IT specialists and tries to be simple in small portions. It should help to imagine the unfamiliar behavior pattern of quanta and to better understand the current development.

After an inevitable excursion into quantum mechanics and photonics, it offers insight into the generation and properties of photons. Common encryption methods are presented. The state of the art in transmission properties is outlined.

Schrödinger’s cat may not be missing in all this, of course.
