Universal quantum cloning beyond noncontextual theory
Min Namkung, Hyang-Tag Lim
Quantum theory fundamentally forbids the perfect copying of an arbitrary unknown quantum state, according to a principle known as the no-cloning theorem. Nevertheless, it is possib…
Contextuality of quantum non-demolition measurement via state discrimination
Min Namkung, Ilhwan Kim, Hyang-Tag Lim
Quantum non-demolition measurements facilitate various quantum technologies, including quantum communication. Notably, their operational structure can be replicated by a classical…
Experimental demonstration of optimal measurement for unambiguously discriminating asymmetric qudit states
Kang-Min Hu, Min Namkung, Myung-Hyun Sohn +1
Identification of nonorthogonal quantum states without error is crucial for various applications in quantum information technology, as well as the foundations of quantum physics. T…
Contextuality-enhanced quantum state discrimination under fixed failure probability
Min Namkung, Hyang-Tag Lim
Quantum state discrimination enables the accurate identification of quantum states, which are generally nonorthogonal. Among various strategies, minimum-error discrimination and un…
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…
Photonic variational quantum eigensolver for NISQ-compatible quantum technology
Kang-Min Hu, Min Namkung, Hyang-Tag Lim
Quantum computers have the potential to deliver speed-ups for solving certain important problems that are intractable for classical counterparts, making them a promising avenue for…
Unified strategy for non-invertible Fisher information matrix in quantum metrology
Min Namkung, Changhyoup Lee, Hyang-Tag Lim
In quantum multi-parameter estimation, the precision of estimating unknown parameters is bounded by the Cramer-Rao bound (CRB), defined via the inverse of the Fisher information ma…
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…
