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,…
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…
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…
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…
Quantum Enhanced Probes of Magnetic Circular Dichroism
Chengyun Hua, Claire E. Marvinney, Seongjin Hong +7
Magneto-optical microscopies, including optical measurements of magnetic circular dichroism, are increasingly ubiquitous tools for probing spin-orbit coupling, charge-carrier g-fac…
Error-mitigated photonic variational quantum eigensolver using a single-photon ququart
Donghwa Lee, Jinil Lee, Seongjin Hong +6
We report the experimental resource-efficient implementation of the variational quantum eigensolver (VQE) using four-dimensional photonic quantum states of single-photons. The four…
Implementation of a 3 x 3 directionally-unbiased linear optical multiport
Ilhwan Kim, Donghwa Lee, Seongjin Hong +4
Linear optical multiports are widely used in photonic quantum information processing. Naturally, these devices are directionally-biased since photons always propagate from the inpu…
Global triplewise information trade-off in quantum measurement
Seongjin Hong, Yong-Su Kim, Young-Wook Cho +3
State disturbance by a quantum measurement is at the core of foundational quantum physics and constitutes a fundamental basis of secure quantum information processing. While quanti…
Experimental implementation of arbitrary entangled operations
Seongjin Hong, Chang Hoon Park, Yeon-Ho Choi +4
Quantum entanglement lies at the heart of quantum mechanics in both fundamental and practical aspects. The entanglement of quantum states has been studied widely, however, the enta…
Reference-Frame-Independent, Measurement-Device-Independent quantum key distribution using fewer quantum states
Donghwa Lee, Seong-Jin Hong, Young-Wook Cho +6
Reference-Frame-Independent Quantum Key Distribution (RFI-QKD) provides a practical way to generate secret keys between two remote parties without sharing common reference frames.…
