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…
Frequency-Division Multiplexed CV-QKD System
Jaehyeok Han, Donghyeok Lee, Minseok Ryu +3
We propose a frequency-division multiplexed (FDM) continuous-variable quantum key distribution (CV-QKD) system with enhanced spectral efficiency through optimized channel spacing o…
Multipartite reference-frame-independent quantum cryptographic communication
Donghwa Lee, Kyujin Shin, Hyang-Tag Lim +2
Reference frame mismatch among communication parties introduces errors in quantum cryptographic protocols. As the number of participants increases, aligning reference frames become…
Entanglement recovery by reversing the effect of noise in quantum repeater
Sewon Jeong, Shrobona Bagchi, Jaehak Lee +4
We propose a method to directly recover the degree of entanglement distributed by entanglement swapping in the presence of noise. Our approach introduces a reversing operation that…
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,…
Ensuring superior learning outcomes and data security for authorized learner
Jeongho Bang, Wooyeong Song, Kyujin Shin +1
The learner's ability to generate a hypothesis that closely approximates the target function is crucial in machine learning. Achieving this requires sufficient data; however, unaut…
