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…
Private Communication over a Bosonic Compound Channel
Florian Seitz, Matteo Rosati, Ángeles Vázquez-Castro +1
It is a common belief that quantum key distribution systems are the one and only information-theoretically secure physical layer security protocol that enables secure data transmis…
Trading Datarate for Latency in Quantum Communication
Zuhra Amiri, Florian Seitz, Janis Nötzel
Low latency and high data rate performance are essential in wireless communication systems. This paper explores trade-offs between latency and data rates for optical wireless commu…
