Maximal coherence of quantum measurement and the resource theory of sharpness
Kyunghyun Baek, Yonggi Jo, Hyunchul Nha
A resource theory of quantum measurement can be addressed in terms of quantum coherence and measurement sharpness, respectively. The former analyzes the off-diagonal structure of P…
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…
Observable criterion for collective entanglement in Boson-lattice system
Mehmet Emre Tasgin, Hyunchul Nha
An optical lattice with cold trapped atoms represents a quantum system of fundamental importance as it enables the study of quantum many-body system in a controllable way. It is th…
Quantum entanglement and extractable work for Gaussian states
Jaewon Lee, Changsuk Noh, Kabgyun Jeong +1
The study of quantum thermodynamics aims to elucidate the role played by quantum principles in the emergent features of quantum thermodynamic processes. Specifically, it is of fund…
