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…
Singularity Selector: Topological Chirality via Non-Abelian Loops around Exceptional Points
Kyu-Won Park, KyeongRo Kim, Kabgyun Jeong
Chirality is more than a geometric curiosity; it governs measurable asymmetries across nature, from enantiomer-selective drugs and left-handed fermions in particle physics to hande…
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…
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 (…
Estimating Quantum Mutual Information Through a Quantum Neural Network
Myeongjin Shin, Junseo Lee, Kabgyun Jeong
We propose a method of quantum machine learning called quantum mutual information neural estimation (QMINE) for estimating von Neumann entropy and quantum mutual information, which…
Sample-size-reduction of quantum states for the noisy linear problem
Kabgyun Jeong
Quantum supremacy poses that a realistic quantum computer can perform a calculation that classical computers cannot in any reasonable amount of time. It has become a topic of signi…
