Quantum Limits of LEO Satellite Beacon Reading
Pere Munar-Vallespir, Marc Geitz, Ãngeles Vázquez-Castro +1
We study the quantum limits of the ELROI beacon concept introduced by Holmes, Weaver, and Palmer. In this concept, a satellite continuously emits a weak optical signal to broadcast…
Infinite-fold Asymptotic Quantum Advantage in Classical Correlation Sensing
Janis Nötzel, Pere Munar-Vallespir
We study the hypothesis testing problem of distinguishing between correlated thermal noise and uncorrelated thermal noise of the same average energy on detectors in asymptotic…
Joint Communication and Eavesdropper Detection on the Lossy Bosonic Channel
Pere Munar-Vallespir, Janis Nötzel, Florian Seitz
We study the problem of joint communication and detection of wiretapping on an optical fiber from a quantum perspective. Our system model describes a communication link that is cap…
Joint Communication and Sensing over the Lossy Bosonic Quantum Channel
Pere Munar-Vallespir, Janis Nötzel
We study the problem of joint communication and sensing for data transmission systems using optimal quantum instruments in order to transmit data and, at the same time, estimate en…
