Maximal extension on converse monogamy of entanglement for tripartite pure states
Junhyeong An, Soojoon Lee
Unlike classical correlations, entanglement cannot be freely shared among multiple parties. This unique feature of quantum systems is known as the monogamy of entanglement. While i…
Photonic Hybrid Quantum Computing
Jaehak Lee, Srikrishna Omkar, Yong Siah Teo +4
Photons are a ubiquitous carrier of quantum information: they are fast, suffer minimal decoherence, and do not require huge cryogenic facilities. Nevertheless, their intrinsically…
Information-theoretic analysis of complex eigenmodes across avoided crossings in open microcavities
Kyu-Won Park, Soojoon Lee, Kabgyun Jeong
Avoided crossings (ACs) are hallmark signatures of mode interaction in quantum and wave systems. Open microcavities whose resonances are naturally described as quasi-normal modes (…
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…
Probing Quantum States over Spacetime Through Interferometry
Seok Hyung Lie, Hyukjoon Kwon
Establishing a notion of the quantum state that applies consistently across space and time could be a crucial step toward formulating a relativistic quantum theory. We give an oper…
Shallow quantum circuit for generating extremely low-entangled approximate state designs
Wonjun Lee, Minki Hhan, Gil Young Cho +1
Random quantum states have various applications in quantum information science. We discover a new ensemble of quantum states that serve as an -approximate state -design while…
