On November 4th at 10:00, Prof. Dr. Juergen Czarske (Faculty Electrical and Computer Engineering/Faculty of Physics/BIOLAS, TU Dresden) will give a talk in room 001 (LNQE) on the topic:
Abstract:
Optical fibers are the backbone of internet. Quantum Key Distribution (QKD), a transmission of keys that are sent between Alice and Bob, achieves security based on quantum mechanics. Entanglement was outlined by Einstein et al. and leading to nonlocal correlations for teleportation in communication (spooky action at a distance). Due to the non-cloning theorem secure data transmission is guaranteed. However, the key rate is many orders of magnitude lower than in classical communication systems. Multimode fibers show promise for improving data rates, but come with the challenge of compensating for scattering effects due to mode conversions. Physics-informed deep learning enables to correct the mode scattering. Perspectives for quantum communication will be discussed.
