On the Optimum Secrecy Outage Probability and Ergodic Secrecy Rate over Wireless Channels
Clement Leroy, Tarak Arbi, Benoit Geller +1
We study the secrecy of wireless channels in the presence of an eavesdropper, where the channels are random and the transmitter only has knowledge of the channel statistics. We inv…

Data Processing Inequality for The Quantum Guesswork
Ilyass Mejdoub, Julien Béguinot, Olivier Rioul
Non-orthogonal quantum states pose a fundamental challenge in quantum information processing, as they cannot be distinguished with absolute certainty. Conventionally, the focus has…

From Classical to Quantum: Explicit Classical Distributions Achieving Maximal Quantum -Divergence
Dimitri Lanier, Julien Béguinot, Olivier Rioul
Explicit classical states achieving maximal -divergence are given, allowing for a simple proof of Matsumoto's Theorem, and the systematic extension of any inequality between cla…
