Quickest Change Detection in Discrete-Time in Presence of a Covert Adversary
Amir Reza Ramtin, Philippe Nain, Don Towsley
We study the problem of covert quickest change detection in a discrete-time setting, where a sequence of observations undergoes a distributional change at an unknown time. Unlike c…

Quickest Change Detection in Continuous-Time in Presence of a Covert Adversary
Amir Reza Ramtin, Philippe Nain, Don Towsley
We investigate the problem of covert quickest change detection in a continuous-time setting, where a Brownian motion experiences a drift change at an unknown time. Unlike classical…

On the Capacity Region of Bipartite and Tripartite Entanglement Switching
Gayane Vardoyan, Philippe Nain, Saikat Guha +1
We study a quantum entanglement distribution switch serving a set of users in a star topology with equal-length links. The quantum switch, much like a quantum repeater, can perform…
