Entanglement Enabled Data Transmission over an Arbitrarily Varying Channel
Janis Nötzel, Florian Seitz
Shared randomness is the central ingredient for stabilizing symmetrizable communication systems against arbitrarily varying jammers. Given the presence of the jammer, however, the…
Transmitting Correlation for Data Transmission over the Bosonic Arbitrarily Varying Channel
Janis Nötzel, Florian Seitz
Shared randomness is the central ingredient for stabilizing symmetrizable communication systems against arbitrarily varying jammers. Given the presence of the jammer, however, the…
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…
Joint Communication and Eavesdropper Detection on the Lossy Bosonic Channel
Pere Munar-Vallespir, Janis Nötzel, Florian Seitz
We study the problem of joint communication and detection of wiretapping on an optical fiber from a quantum perspective. Our system model describes a communication link that is cap…
