Estimation of Quantum Umlaut Information
Beomjoon Kim, Donghwa Ji, Kabgyun Jeong
Quantifying correlations is important for understanding how quantum states and channels support information processing. Quantum umlaut information connects such correlations to…
Optimal (Parallel) Spooky Pebbling on Binary Trees
Mingyu Lee, Sanghyun Lee, Kabgyun Jeong
Pebble games model computations under a fixed space budget. Spooky pebbling allows quantum memory to be released by measurement, with the resulting phases corrected later. We study…
Entanglement Structure Across Phase Transitions in 1D Rydberg Atom Arrays
Hyeonjun Yeo, Kabgyun Jeong, Hyunchul Nha
Multipartite quantum entanglement plays a crucial role in the emergence of different quantum phases and their transitions in quantum many-body systems. It is of general interest to…
Concentration of Measure Phenomena for Quantum States on a Higher Dimensional Equator
Kabgyun Jeong
We revisit Lévy's lemma, a widely used analytical tool in quantum information theory. Concentration inequalities quantify the phenomenon in which Lipschitz observables concentrate…
Fundamental Limitations of Post-Quantum Cryptographic Architectures
Jiho Jung, Donghwa Ji, Mingyu Lee +1
Modern lattice-based cryptography, particularly the learning with errors paradigm, relies on injecting artificial noise to secure data against quantum adversaries. This study syste…
Projected Dynamic Programming for Sequential Quantum State Discrimination
Jaehun Jeong, Donghwa Ji, Hyunjun Jang +1
Sequential Quantum State Discrimination (SQSD) can be naturally framed as a sequential decision-making problem: at each time step, an agent must decide whether to perform an additi…
