When Routes Run Out: Adversarial Co-Learning and Explainable Robustness in Quantum Repeater Networks
Brennan Bell, Inti Gabriel Mendoza Estrada, Andreas Trügler +1
We study an adversarial bandit problem for entanglement-based quantum-network routing over a modest graph corpus. Alice selects an end-to-end repeater route for an Ekert-91 protoco…
Hardware-Agnostic Modeling of Quantum Side-Channel Leakage via Conditional Dynamics and Learning from Full Correlation Data
Brennan Bell, Andreas Trügler, Konstantin Beyer +1
We study a sequential coherent side-channel model in which an adversarial probe qubit interacts with a target qubit during a hidden gate sequence. Repeating the same hidden sequenc…
High-dimensional quantum communication with scalable photonic entanglement in time and frequency
Kai-Chi Chang, Murat Can Sarihan, Nicky Kai Hong Li +13
High-dimensional photonic entanglement holds significant promise for advancing quantum communication, computation, and metrology. For example, large-alphabet quantum communication…
Radio-Frequency Side-Channel Analysis of a Trapped-Ion Quantum Computer
Giorgio Grigolo, Dorian Schiffer, Lukas Gerster +2
Analogously to classical computers, quantum processors exhibit side channels that may give attackers access to potentially proprietary algorithms. We identify and exploit a previou…
Feedback-Induced Advantage in Quantum Clockworks
Jakob Miller, Paul Erker
Atomic frequency standards have achieved steadily increasing precision over the past seventy years, enabled in part by feedback mechanisms that stabilise their output. In parallel,…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
