Demonstration of subspace-search variational quantum eigensolver using photonic orbital angular momentum qudits
Kang-Min Hu, Myung-Hyun Sohn, Yong-Su Kim +3
Accurate excited state energies are essential for interpreting fluorescence and photochemical processes, yet variational quantum eigensolvers (VQEs) on noisy intermediate-scale qua…
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…
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…
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…
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…
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…
