Quantum cryptography makes it possible for the first time to generate a secret key for secure communication in a tap-proof manner. Today, commercial systems are available that guarantee secure transmission of messages at high rates in combination with conventional encryption devices.
However, the range is limited due to the absorption of light in glass fibres. Future quantum networks will enable communication between quantum computers and also efficient, secure key generation over long distances. This is all very promising, but there is still a long way to go.
The "Physik Modern" lecture series in the quantum year 2025 offers insights into various areas of quantum physics, from the history of the theory's origins to its postulates and current research. The lectures are organized by LMU Physics and the Cluster of Excellence Munich Center for Quantum Science and Technology and present current research areas of the Faculty of Physics at LMU Munich and the participating Max Planck Institutes in a generally understandable way. The lecture series is aimed at a broad public interested in the subject. After the lecture there will be room for discussion and personal dialogue.
The lectures take place on the specified Thursdays at 19:15 in lecture theatre H030, Schellingstr. 4, or N120, Geschwister-Scholl-Platz 1.
