Distributed variational quantum computing with deterministic entanglement tuning
Ilhwan Kim, Yong-Su Kim, Kwang Jo Lee +3
Distributed quantum computing offers a scalable route to quantum information processing by entangling spatially separated processors. Although gate teleportation enables universal…
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…
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…
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…
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,…
