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…
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…
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…
Non-Gaussian entanglement criteria for atomic homodyne detection
Jaehak Lee, Jiyong Park, Jaewan Kim +2
Homodyne measurement is a crucial tool widely used to address continuous variables for bosonic quantum systems. While an ideal homodyne detection provides a powerful analysis, e.g.…
-depth-optimized Quantum Search with Quantum Data-access Machine
Jung Jun Park, Kyunghyun Baek, M. S. Kim +3
Quantum search algorithms offer a remarkable advantage of quadratic reduction in query complexity using quantum superposition principle. However, how an actual architecture may acc…
