Covert Quantum Communication - Evan Anderson @ Quantum Village, DEF CON 32

Abstract: Given access to the start time, duration, method of encoding, and an all-powerful quantum receiver, could you perform the "simple" task of detecting whether two or more parties were attempting to communicate? Covert communication, or low probability of detection, demonstrates that it is possible to hide signals within noise so effectively that even an all-powerful quantum adversary would have a vanishing probability of detecting the signal’s presence. In this talk, I'll provide a high-level overview of covert communication and its extension to the quantum regime. I'll discuss the theoretical underpinnings of covert quantum communication, and how we can practically implement such a system. Finally, I'll discuss the ethical considerations of this work and why we should care about it. Speaker Bio: Driven by a deep curiosity about the nature of information, Evan Anderson transitioned from software engineering to pursue a PhD in quantum information theory and photonic quantum information processing. He is curious about all aspects of information, from its fundamental structure within physics to how we manipulate it to suit our needs in day-to-day conversations. Evan is currently in his final year as a PhD student at the University of Arizona, the home of the Center for Quantum Networks, where his research primarily focuses on covert communication over quantum channels and quantum coding theory. ** Quantum Village ** PLEASE LIKE AND SUBSCRIBE TO HELP GET OUR CONTENT TO QUANTUM HACKERS EVERYWHERE!
