Detecting Symmetrizability in Physical Systems
Florian Seitz, Janis Nötzel
We study the problem of data transmission under the influence of a jammer, which is typical for wireless systems and commonly modeled as an arbitrarily varying channel (AVC) in inf…

Data Transmission over a Bosonic Arbitrarily Varying Quantum Channel
Janis Nötzel, Florian Seitz
Arbitrarily varying channels offer a powerful framework for analyzing the robustness of quantum communication systems, especially for classical-quantum models, where the analysis d…

Capacity Formulas for the Lossy Bosonic Compound Wiretap Channel
Florian Seitz, Janis Nötzel
We consider the bosonic compound wiretap channel. A pair of lossy channels connects a sender with both a (legitimate) receiver and an eavesdropper. The sender and receiver have onl…
