Covert Communication Over a Quantum MAC with a Helper
Hassan ZivariFard, Rémi A. Chou, Xiaodong Wang
We study covert classical communication over a quantum multiple-access channel (MAC) with a helper. Specifically, we consider three transmitters, where one transmitter helps the ot…
One-Shot Secret Sharing with Monotone Access Structures over Classical-Quantum Broadcast Channels
Truman Welling, Rémi A. Chou, Aylin Yener
We consider a secret sharing setting with a monotone access structure involving a control node and users, connected via a classical-quantum broadcast channel whose input is con…
Secret-Key Generation from Private Identifiers under Channel Uncertainty
Vamoua Yachongka, Rémi A. Chou
This study investigates secret-key generation for device authentication using physical identifiers, such as responses from physical unclonable functions (PUFs). The system includes…
Covert Communication and Key Generation Over Quantum State-Dependent Channels
Hassan ZivariFard, Rémi A. Chou, Xiaodong Wang
We study covert communication and covert secret key generation with positive rates over quantum state-dependent channels. Specifically, we consider fully quantum state-dependent ch…
