A threshold for maximal Schmidt number from spectrum

Junhyeong An, Soojoon Lee

The Schmidt number quantifies the dimensionality of entanglement in bipartite quantum states. We investigate when the spectrum of a state on alo…

Beyond the Positive Partial Transpose Squared Conjecture: The Qutrit Case

Junhyeong An, Soojoon Lee

Entanglement swapping is a fundamental operation in quantum repeaters for establishing entanglement between distant parties. The positive partial transpose (PPT) squared conjecture…

Correlated Entropic Uncertainty as a Signature of Exceptional Points

Kyu-Won Park, Soojoon Lee, Kabgyun Jeong

Non-Hermitian physics has become a fundamental framework for understanding open systems where gain and loss play essential roles, with impact across photonics, quantum science, and…

Chaos-controlled switching between entanglement and coherence

Kyu-Won Park, Soojoon Lee, Kabgyun Jeong

Controlling entanglement and coherence is central to quantum information, yet the two resources often exhibit antagonistic trends and are difficult to optimize within a single plat…

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…

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 (…

Maneuvering measurement-coherence into measurement-entanglement

Ho-Joon Kim, Soojoon Lee

Quantum dynamics governs the transformation of static quantum resources, such as coherence and entanglement, in both quantum states and measurements. Prior studies have established…
