Universal Operational Privacy in Distributed Quantum Sensing
Min Namkung, Dong-Hyun Kim, Seongjin Hong +3
The paper proposes a universal, experimentally accessible privacy criterion for distributed quantum sensing based on the Fisher information matrix, and demonstrates experimentally…
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,…
Persistent quantum advantage with definite photon-number states in lossy multiple-phase estimation
Min Namkung, Dong-Hyun Kim, Seongjin Hong +2
Multiple-phase estimation exploiting quantum states has broad applications in novel sensing and imaging technologies. However, the unavoidable presence of lossy environments in pra…
Optimal multiple-phase estimation with multi-mode NOON states against photon loss
Min Namkung, Dong-Hyun Kim, Seongjin Hong +3
Multi-mode NOON states can quantum-enhance multiple-phase estimation in the absence of photon loss. However, a multi-mode NOON state is known to be vulnerable to photon loss, and i…
Implementation of CU gates and its application in a remote-controlled quantum operation
Byungjoo Kim, Seongjin Hong, Yong-Su Kim +2
Recently, remote-controlled quantum information processing has been proposed for its applications in secure quantum processing protocols and distributed quantum networks. For remot…
