Hierarchical Joint Source-Channel Coding with Constrained Information Leakage

Yiqi Chen, Holger Boche, Marc Geitz

This paper studies the hierarchical joint source-channel coding with information leakage constraint in the first-phase reconstruction and distortion constraints. The receiver's acc…

Lossy Source Coding with Broadcast Side Information

Yiqi Chen, Holger Boche, Marc Geitz

This paper considers the source coding problem with broadcast side information. The side information is sent to two receivers through a noisy broadcast channel. We provide an outer…

Quantum Limits of LEO Satellite Beacon Reading

Pere Munar-Vallespir, Marc Geitz, Ángeles Vázquez-Castro +1

We study the quantum limits of the ELROI beacon concept introduced by Holmes, Weaver, and Palmer. In this concept, a satellite continuously emits a weak optical signal to broadcast…

Quantum Physical Unclonable Function based on Chaotic Hamiltonians

Soham Ghosh, Holger Boche, Marc Geitz

Quantum Physical Unclonable Functions (QPUFs) are hardware-based cryptographic primitives with strong theoretical security. This security stems from their modeling as Haar-random u…
