Causal Fisher-Information Inequalities: Classical Causal Model Falsification and Metrological Advantage
Jeongho Bang, Su-Yong Lee
Fisher-information inequalities have recently been used as operational witnesses of nonclassical metrological behavior, but their physical meaning is often tied to a particular nar…
Universal Operational Privacy in Distributed Quantum Sensing
Min Namkung, Dong-Hyun Kim, Seongjin Hong +3
Privacy is a fundamental requirement in distributed quantum sensor networks, where multiple clients estimate spatially distributed parameters using shared quantum resources while i…
Distributed quantum sensing with multi-mode states
Dong-Hyun Kim, Seongjin Hong, Yong-Su Kim +4
Distributed quantum sensing, which estimates a global parameter across distant nodes, has attracted significant interest for applications such as quantum imaging, sensor networks,…
Quantum key distribution using vacuum-one-photon qubits: maximum number of transferable bits per particle
Su-Yong Lee, Se-Wan Ji, Hai-Woong Lee +2
Quantum key distribution schemes which employ encoding on vacuum-one-photon qubits are capable of transferring more information bits per particle than the standard schemes employin…
